SUMMARY:Software Architecture for High Data Rate Wireless Body Sensor Applications
DESCRIPTION:Software Architecture for High Data Rate Wireless Body Sensor Applications\nby Seung-Mok Yoo \nFor wireless body area sensor networks\, the wearable nodes are highly constrained by low power\, low cost\, and small size while deliverly high throughput and low latency in a multiple access environment. To accomplish these goals\, the hardware must be kept simple\, and as a result\, the traditional abstractions with separate layers of the protocol stack and application must be merged and made as streamlined as possible. This dissertation identifies and removes two bottlenecks with data transfers: one is between the base station and its sensor nodes\, and the other is within the sensor node. \nFirst\, we propose a thin-server\, fat-client architecture. It supports a pulling protocol that achieves intra-network collision-free multiple access as in TDMA but without the time synchronization overhead. It also achieves high data throughput of air bandwidth and adaptivity of CSMA protocols but without collision or complexity on the node side. \nSecond\, for intra-node transfers\, another known bottleneck is the system bus. We identify the double-transaction problem\, which is common to SPI\, DMA\, and other interfaces. We propose the Master-Handoff Protocol to eliminate the redundant transaction and improve latency significantly\, and it is compatible with existing controllers. It not only halves the data transfer time but also achieves energy reduction. Together\, these techniques enable highly constrained hardware to meet strict size and power constraints for high wearability without sacrificing performance.

SUMMARY:No-Instruction-Set-Computer (NISC) Modeling and Compilation Abstract
DESCRIPTION:No-Instruction-Set-Computer (NISC) Modeling and Compilation Abstract\nby Mehrdad Reshadi \nToday\, depending on the size and complexity of a program\, there are two options for synthesizing a program to hardware: (1) using High Level Synthesis (HLS)\, and (2) using Application-Specific-Instruction-Processor (ASIP). \nTraditional HLS techniques can only support relatively small applications and do not give enough control to the designer over the quality of results. Poor quality of results and limited application domain has prevented the HLS from wide spread usage. \nEmbedded processors often run only one or a few applications in the life-time of the system. Therefore\, they can be customized for the target applications and significantly improve the quality of the embedded system in terms of cost\, performance\, power consumption\, etc. This is the goal in ASIP approaches. Instruction-based architectures limit the customizations because: (a) hardware designer is limited by instruction coding\, size and complexity of the decoder; (b) compilers can support certain class of instructions and hence instructions cannot be very complex; and (c) manually updating compilers to incorporate the custom instructions is not practical and developing compilers that automatically utilize hardware customizations through new custom instructions is very complex. \nIn this talk I present a new design approach called NISC (No-Instruction-Set-Computer) Technology. In NISC\, the datapath and controller are generated in two different phases. First the datapath is generated or selected from a database based on the application behavior. At the core of NISC technology\, there is a cycle-accurate compiler that maps a given application directly on a given datapath and generates the control words (CWs) that control the datapath resources in every clock cycle. The NISC architecture style is similar to the old nanocode machines. However\, instead of using nanocodes inside the process for implementing the microcodes and in turn instructions\, in NISC the nanocode (CWs) are directly used to program the datapath. \nNISC simplifies customization and allows designer to fully control design quality. NISC simplifies ASIP (Application-Specific-Instruction-Processor) approach by removing the complex task of finding and designing “most profitable” custom instructions. In NISC only the datapath needs to be specified and NISC compiler generates code “as if” each basic block of the program is executed with one custom instruction. On the other hand\, NISC improves resource constrained HLS techniques by adding the connectivity constraints\, on top of the traditional resource constraints\, into synthesis process. This enables the designer to control every thing in datapath including wires\, which are becoming increasingly more critical in newer technologies. In fact NISC combines the ASIP and HLS techniques. \nTo realize the NISC Technology design flow\, several challenging categories of problems must be solved. Mainly we need: \n1. Techniques for efficiently designing and customizing a datapath for an application\n2. Techniques for efficiently compiling any application on any given datapath\n3. Techniques for efficiently synthesizing a controller from the output of compiler and then generating synthesizable code for different target implementations. \nIn my thesis\, I focus on the compilation problems to enable practical use of NISC IPs in a system. A working compiler and other NISC tools are available for public use from NISC websitehttps://www.cecs.uci.edu/~nisc/. An online version of the tools can be also directly accessed at this website.

SUMMARY:Jelena and Gajski Receive IESS Best Paper Award
DESCRIPTION:Jelena Trajkovic\, a PhD candidate in computer science\, and Professor Daniel D Gajski\, received best paper award at the second International Embedded System Symposium that took place in Irvine\, California from May 30th to June 1st 2007. Their paper is titled “Automatic Data Path Generation from C Code for Custom Processors.” The paper was selected from over 60 submissions on the basis of technical quality and presentation. The authors of the best paper received an Altera Nios II Embedded Development Kit.\nAutomatic generation of architectures from C code is a fundamentally novel way of addressing the problem of system design. In traditional design methods\, architecture is assumed as fixed for implementing an application. Compilers must then figure out the best mapping of the application on the given architecture. This method may result in poor performance because the given architecture may not carry the best features to execute the application code. Moreover\, the architecture may carry features that are never used by the application\, resulting in wasted power and area. Architecture generation from C code attempts to solve this problem by automatically creating an architecture that “matches” the C code. \nIn their paper\, Jelena and Prof. Gajski present first results for the generation of matching architecture from C code. They address the selection of function units to meet performance goals while maximizing architecture utilization. Their experimental results demonstrate that the architecture could be generated for large C code\, including an MP3 decoder with over 14K lines of code\, under an hour. The optimizations improved architecture utilization by 30 to 60 percent while meeting performance constraints. \nCECS congratulates the researchers on their achievement and wishes them success in their future endeavors.

SUMMARY:Payam Heydari Wins Guillemin-Cauer
DESCRIPTION:Payam Heydari\, associate professor of electrical engineering and computer science\, and a Calit2 academic affiliate at UC Irvine\, has won this year’s prestigious Guillemin- Cauer Award from the IEEE Circuits and Systems Society. Heydari is also the recipient of the 2005 IEEE Circuits and Systems Society Darlington Award\, which puts him in an elite group of only seven researchers who\, in the 40-year history of the awards\, have received both.\nHeydari was recognized for his paper “Model-Order Reduction Using Variational Balanced Truncation with Spectral Shaping\,” which was published in the IEEE Transactions on Circuits and Systems\, Vol. 53\, April 2006. \nThe latest integrated circuit technology – geared to the nanoscale – continues to create new possibilities for designers to substantially reduce chip size and increase speed. The technology\, however\, also presents challenges\, most notably to the yield and reliability of the circuits and on-chip wires. \nIt is essential to capture statistical fluctuations caused by process variations\, but testing such complicated systems can require days of computer simulation. Heydari’s approach dramatically reduces the time needed for this statistical modeling from days to just minutes. It significantly reduces the order of the original system while retaining important circuit characteristics\, such as frequency and timedomain. Most notably\, this technique accounts for statistical variation due to changes in process. \nIn addition\, Heydari’s approach provides a proven boundary for error between the reduced order model and the original system. The work has since been the foundation for several key papers published by other researchers on the same topic. \nThe Guillemin-Cauer Award recognizes the best journal paper published in IEEE Transactions on Circuits and Systems during the two calendar years preceding the award. The award is based on general quality\, originality\, contributions\, subject matter and timeliness.

SUMMARY:Bita Gorjiara Takes Hami and Best Paper Award
DESCRIPTION:Bita Gorjiara has won the prestigious Hami Award of Excellence in Engineering Education for the year 2007. Sponsored by the Fanni Reunion Foundation\, the Hami award recognizes outstanding M.Sc. and Ph.D. graduates with a previous degree from University of Tehran. Each year\, Hami award is given to one or two students with excellent academic record in terms of GPA\, number of publications\, and overall contribution in their field of study. Bita has also received the Best Student Paper Award for her journal paper\, “Ultra-Fast and Efficient Algorithm for Energy Optimization by Gradient-based Stochastic Voltage and Task Scheduling\,” which has also been accepted for publication in ACM Transactions on Design Automation of Electronic Systems (TODAES).\nThis paper award is an honor given by the EECS department for first-time authors. In her paper\, co-authored by Professor Bagherzadeh and Professor Chou\, Bita proposes an ultra-fast and voltage scheduling algorithm called Adaptive Stocahstic Gradient Voltage-and-Task Scheduling (ASG-VTS) that is used for power optimization of designs with voltage islands. This unique technique was shows to surpass the energy savings of previously published results while reducing number of voltage transitions. Compared to an optimal ILP algorithm\, her technique converges 1000 times faster while generating results as good as the optimal solution. She has also developed a web-based tool for her algorithm that allows researchers to capture the model of their system and run ASG-VTS. Research groups use Bita’s tool for evaluating new algorithms\, and some universities have used as part of their course curriculum. \nCurrently\, and for the past three years\, Bita has been working on No-Instruction-Set Computer (NISC) project under supervision of Prof. Gajski. She has developed an Architecture Description Language (ADL) for NISC called GNR that is used for automatic generation of RTL code. She has also proposed techniques to reduce power consumption and code size of NISCs while improving their performance via architecture customization.

SUMMARY:Software for Embedded Systems: Serializing Compilers and Its Applications
DESCRIPTION:Software for Embedded Systems: Serializing Compilers and Its  Applications\nby Andre Costi Nacul \nIn order to cope with the complexity of systems\, engineers are  turning to software. In part\, well established programming models\,  highly evolved tool chains\, ease of software reuse\, availability of  open-source software\, and expeditious nature of the design-compile- execute paradigm make developing a new feature in software more  favorable. It is assumed that\, in coming years\, more than 70% of  product features are going to be supported by software.\nIn particular\, the concurrent programming paradigm is an ideal model  of computation for design of embedded systems\, which often encompass  inherent concurrency. The support for concurrent programming is  usually provided by a real-time operating system (RTOS). Usually\, an  RTOS is a generic framework which can be used across a large number  of processors and applications. An RTOS provides coarse grained  timing support\, and is loosely coupled to the running tasks. As a  result\, an RTOS is seldom optimized for any particular application. \nDespite of all the recent enhancements to compiler technology\,  current compilers have a limited understanding of tasks. Generally\,  the compiler is tightly integrated with the platform. Traditional  compilers are efficient in using platform specific resources\, and in  generating an optimized instruction sequence. Current compiler  technology is capable of extracting instruction-level parallelism  (ILP)\, to varying degrees. Traditionally\, ILP comes from optimizing  loops\, and most likely analyzes code at the basic block level. Today\,  there is no compiler that can detect parallelism at the task level.  Parallelism detection is usually restricted to basic block  structures\, or higher level constructs such as loops. Moreover\,  compilers also lack support for timing constraints of real-time  applications. \nIn this thesis\, we propose an alternative to an RTOS based on the  idea of serializing compilers. A serializing compiler is an automated  software synthesis methodology that can transform a multitasking  application into an equivalent and optimized monolithic sequential  code\, to be compiled with the embedded processor’s native optimizing  compiler. The serializing compiler can analyze the tasks at compile  time and generate a fine-tuned\, application specific infrastructure  to support multitasking\, resulting in a more efficient executable  than one that is intended to run on top of a generic RTOS. By having  control over the application execution and context switches\, the  serializing compiler enables the fine grain control of task timing  while enhancing overall performance. Our serializing compiler  technology strengthens existing compilers\, making them timing and  task-aware. \nThe Phantom Compiler\, our implementation of a serializing compiler\,  provides a fully automated mechanism to synthesize a single threaded\,  ANSI C/C++ program from a multithreaded C/C++ (extended with POSIX)  program. The Phantom generated code is highly tuned for the input  application. With a serializing compiler such as the Phantom  Compiler\, it is possible to generate a multitasking infrastructure  that is small in size\, very efficient when context-switching\, and  customized for each specific application.

SUMMARY:New Strategies for System-Level Design
DESCRIPTION:New Strategies for System-Level Design: Where to Go?\nKeynote Talk \n\n\n\n\nSpeaker\n\n\nProfessor Gajski \nElectrical Engineering and Computer Science\nUniversity of California at Irvine\n\n\n\n \n\n\n \n\n\n\nLocation\n\n\nThe 10th IEEE Workshop on Design and Diagnostics of Electronic Circuits and Systems\, Kraków\, Poland\n\n\n\n \n\n\n \n\n\n\nDate\n\n\nApril 11\, 2007\n\n\n\n \n\n\n \n\n\n\nAbstract\n\n\nWith complexities of Systems-on-Chip rising almost daily\, the design community has been searching for new vision that can handle given complexities with increased productivity and decreased times-to-market. The obvious solution\, such as increasing levels of abstraction\, introducing variety of IPs or offering new design languages will not solve the problem but only prolong the present status of inefficiency and confusion. What is needed is a drastic change in design automation for complex systems that consist of software and hardware. In order to design such systems efficiently\, we need a new approach with a new design flow\, with new models with well defined semantics and a new formalism that will support system synthesis and verification of software and hardware. \nIn order to find the solution\, we will look first at the system gap between SW and HW designs and derive requirements for the design flow that includes software as well as hardware. In order to enable new EDA tools for model generation\, simulation\, synthesis and verification\, the design flow has to be well defined with unique abstraction levels\, model semantics and model transformations corresponding to design decisions made by the designers. We will introduce the concept of model algebra that supports this approach and can serve as an enabler for the extreme makeover of EDA. We will support this concept with hard data and finish with a prediction and a roadmap toward the final goal of increasing productivity by several orders of magnitude while reducing expertise level needed for design of complex systems to the basic principles of design science only.\n\n\n\n\n\n\n\n\n\n\nSlides\n\n\nDownload slides\n\n\n\n \n\n\n \n\n\n\nBiography\n\n\n  \n\n \n\nDaniel Gajski\, a leader in the areas of embedded systems\, design methodologies and languages\, headed the research teams that created new design concepts\, methodologies\, tools and languages. He was instrumental in developing formalisms such as Y-chart\, and numerous algorithms for high-level synthesis\, the definition of the control-data-flow-graph (CDFG) and finite-state-machine with data (FSMD)\, system level languages such as SpecCharts and SpecC\, and design tools such as SpecSyn and Embedded-System Environment. Many of these concepts have been adapted by academia and industry in the last 25 years. \nGajski directs the UCI Center for Embedded Computer Systems\, with a research mission to incorporate embedded systems into automotive\, communications\, and medical applications. He has authored over 300 papers and numerous textbooks\, including Principles of Digital Design (Englewood Cliffs\, NJ: Prentice Hall\, 1997) that has been translated into several languages. \nHe holds Dipl. Ing. and M.S. degrees in electrical engineering from the University of Zagreb\, Croatia\, and a doctoral degree in computer and information sciences from the University of Pennsylvania\, Philadelphia. After 10 years as Professor at University of Illinois he has joined UCI\, where he presently holds The Henry Samueli Endowed Chair in Computer System Design.

SUMMARY:Content Annotation for Power and Quality Trade-Offs in Mobile Multimedia Systems
DESCRIPTION:Content Annotation for Power and Quality Trade-Offs in Mobile Multimedia Systems\nby Radu Cornea \nRecent advances in processor\, wireless and graphics technology have fueled a convergence of traditional PDA and cellphone functionality into complex\, media-centric mobile devices. A popular class of applications emerging on these platforms is represented by multimedia\, in particular content streaming (video\, audio). However\, all this added functionality has not come without an expense in one of the most important area for a mobile device: battery life. Multimedia streaming in particular\, with its stringent compu tation\, communication and quality of service requirements further aggravates battery life on these already constrained devices. \nOn the other hand\, multimedia applications have very regular execution patterns\, the only changes being introduced by variations in the data stream itself. This thesis presents a new way to optimize power consumption for multimedia applications\, based on content analysis and annotations. Specifically\, we pre-process the multimedia streams and utilize annotations to capture and carry content-related information to the client device at the receiving end. Annotations allow us to perform more accurate and aggressive optimizations\, with knowledge of the actual content and without relying to less accurate prediction models. \nWe investigate the use of annotation for content-aware optimizations at all level of abstraction (hardware/OS\, network\, application) for the most important system components in a mobile device: CPU/memory\, network interface\, display. Our experimental results show that important energy savings can be achieved for all these components through annotations. Finally\, we integrate the techniques at all levels of abstraction for an increased user experience and battery functionality. We also show how cross-layer trade-offs between power and quality can lead to even higher energy savings with minimal quality degradation.

SUMMARY:Multiprocessor System-on-Chip Data Memory Customization for Embedded Array-Intensive Applications
DESCRIPTION:Multiprocessor System-on-Chip Data Memory Customization for Embedded Array-Intensive Applications\nby Ilya Michailovich Issenin \nWith increasing processing power demands of embedded applications and technology advances\, Multiprocessor Systems-on-Chip (MPSoCs) become prevalent in embedded systems. The memory subsystem is a large and critical contributor to both energy and performance of such systems\, requiring system designers to perform exploration of low power memory organizations. In this dissertation we present an automated approach for data memory subsystem customization for streaming applications. Our approach allows modification of the program to use custom scratch pad memory configurations comprising a hierarchical set of buffers for local storage of frequently reused data. Our data reuse analysis technique provides the system designer with a wide range of customized memory hierarchy organizations with different size and energy profiles and enables the system designer to explore feasible memory subsystem solutions that satisfy power and area constraints while still meeting task deadlines\, both for uniprocessor and multiprocessor systems. \nIn modern multiprocessor embedded systems the communication subsystem also plays an important role in determining overall system power consumption and performance. We propose novel approaches that enables energy-aware co-synthesis of both memory and communication architectures for streaming applications targeting hierarchical bus-based and Network-on-Chip communication architectures. Our techniques achieve significant reduction in memory and communication subsystems energy consumption for data dominant applications\, and allow system designers to explore custom scratch pad memory configuration for a range of power and area constraints. \nThesis\nSlides

SUMMARY:Love and Eli Take FPL’06 Best Paper Award
DESCRIPTION:Love Singhal\, a Ph.D. candidate in computer science\, and professor of computer science Eli Bozorgzadeh received the Best Paper Award at the 2006 IEEE International Conference on Field Programmable Logic and Applications (FPL’06) that took place in Madrid\, Spain\, August 28-30 2006. The awarded paper is titled “Multi-layer Floorplanning on a Sequence of Reconfigurable Designs.”\nThe dynamic partial reconfigurability of programmable devices such as FPGAs is characterized by their ability to reconfigure subsets of their logic and routing resources at runtime. This intrinsic dynamic reconfiguration results in accommodation of complex and dense designs\, on-fly adaptivity\, and design modification. Reconfigurable module can be a new coprocessor implemented on a FPGA device\, an upgraded implementation of the existing module\, or a reconfigured memory block. However\, partial reconfiguration comes with the cost of reconfiguration overhead delays. In order to reduce the reconfiguration overhead\, two consecutive similar sub-designs should be placed in the same locations to get the maximum reuse of common components. \nIn this paper\, a new multi-layer sequencepair- based floorplanner is proposed for a given sequence of reconfigurable designs. In the experiments\, compared to a traditional sequential floorplanner\, the new floorplanner removes infeasibility in many designs\, and provides faster timing closure. \nFPL is the first and largest conference on programmable logic which encompasses a wide range of research area on FPGAs\, including applications\, novel system architectures and CAD tools\, embedded processors\, dynamic recon figuration\, etc. The acceptance rate in FPL 2006 was 28 percent\, out of 307 submissions.
