SUMMARY:Ultra Low-Power VLSI through Co-Optimization of Architecture and Circuit-Level Design
DESCRIPTION:Ultra Low-Power VLSI through Co-Optimization of Architecture and Circuit-Level Design\n  \n\n\n\n\nSpeaker\n\n\nDr. Hiroshi Nakamura\nUniversity of Tokyo\, Japan\n\n\n\n\n\n\n\n\n\n\nCECS Host\n\n\nProfessor Nikil Dutt\n\n\n\n\n\n\n\n\n\n\nLocation\n\n\nDonald Bren Hall (DBH) 3011\n\n\n\n\n\n\n\n\n\n\nDate & Time\n\n\nMay 4\, 2009\nRefreshments at 1:30 pm\, Lecture begins at 2:00pm (Lecture Cancelled)\n\n\n\n\n\n\n\n\n\n\nAbstract\n\n\nWe are currently conducting a research project called ‘Innovative Power Control for Ultra Low-Power and High-Performance System LSIs’ supported by JST (Japan Science and Technology Agency). In this talk\, we first briefly introduce the project\, and then present a fine grain power gating processor which is currently under development. Fine grain power gating is a promising way to reduce leakage power. However\, applying fine grain power gating at very close intervals suffers from energy overhead caused by power gating itself. To overcome this problem\, co-optimization between architecture and circuit-level design is important. We will present several techniques about this issue and discuss the experimental results.\n\n\n\n\n\n\n\n\n\n\nBiography\n\n\n  \n\nHiroshi Nakamura received the BE\, ME\, and Ph.D. degree in Electrical Engineering from the University of Tokyo in 1985\, 1987\, and 1990\, respectively. From 1990 to 1996\, he was a faculty of Institute of Information Sciences and Engineering at University of Tsukuba. He was a visiting associate professor at the University of California\, Irvine from 1996 to 1997. He is currently an Associate Professor of Department of Information Physics and Computing at the University of Tokyo. His research interests include high-performance and low-power processor architecture\, VLSI design\, and dependable computing. He received the best paper award from IPSJ (Information Processing Society of Japan) in 1994 and Sakai Special Researcher Award from IPSJ in 2002.

SUMMARY:Nonlinear Symbolic Program Analysis for Increased Parallelization
DESCRIPTION:Nonlinear Symbolic Program Analysis for Increased Parallelization\n\n\n\n\nSpeaker\n\n\nProfessor Kleanthis Psarris \nDepartment of Computer Science\nThe University of Texas at San Antonio\, TX\n\n\n\n\n\n\n\n\n\n\nCECS Host\n\n\nProfessor Alex Nicolau\n\n\n\n\n\n\n\n\n\n\nLocation\n\n\nMcDonnell Douglas Auditorium\n\n\n\n\n\n\n\n\n\n\nDate & Time\n\n\nMarch 9\, 2009\nRefreshments at 2:30 pm\, Lecture begins at 3:00pm\n\n\n\n\n\n\n\n\n\n\nAbstract\n\n\nHigh end parallel and multi-core processors rely on compilers to perform the necessary optimizations and exploit concurrency in order to achieve higher performance. However\, source code for high performance computers is extremely complex to analyze and optimize. In particular\, program analysis techniques often do not take into account complex expressions during the data dependence analysis phase. Most data dependence tests are only able to analyze linear expressions\, even though non-linear expressions occur very often in practice. Therefore\, considerable amounts of potential parallelism remain unexploited. In this talk we propose new data dependence analysis techniques to handle such complex instances of the dependence problem and increase program parallelization. Our method is based on a set of polynomial time techniques that can prove or disprove dependences in source codes with non-linear and symbolic expressions\, complex loop bounds\, arrays with coupled subscripts\, and if-statement constraints. In addition our algorithm can produce accurate and complete direction vector information\, enabling the compiler to apply further transformations. To validate our method we performed an experimental evaluation and comparison against the I-Test\, the Omega test and the Range test in the Perfect and SPEC benchmarks. The experimental results indicate that our dependence analysis tool is accurate\, efficient and more effective in program parallelization than the other dependence tests. The improved parallelization results into higher speedups and better program execution performance in several benchmarks.\n\n\n\n\n\n\n\n\n\n\nBiography\n\n\n  \n\nKleanthis Psarris is Professor and Chair of the Department of Computer Science at the University of Texas at San Antonio.

SUMMARY:SystemCoDesigner: Automatic Design Space Exploration and Rapid Prototyping from Behavioral Models
DESCRIPTION:SystemCoDesigner: Automatic Design Space Exploration and Rapid Prototyping from Behavioral Models\n\n\n\n\nSpeaker\n\n\nDr. Christian Haubelt\nUniversity of Erlangen-Nuremberg\, Germany\n\n\n\n\n\n\n\n\n\n\nLocation\n\n\nEngineering Tower\, Room 331\, University of California\, Irvine\n\n\n\n\n\n\n\n\n\n\nDate & Time\n\n\nJune 13 \, 2008\nTalk begins 11:00am\nRefreshments at 10:30am\n\n\n\n\n\n\n\n\n\n\nAbstract\n\n\n80% of all design decisions are made in the first 20% of the design time. Thus\, a substantiated knowledge about possible solutions is mandatory in early design phases in order to design high quality products. SystemCoDesigner is a software tool for automatic design space exploration at the electronic system level and for platform-based prototyping of hardware/software systems. By exploring the design space\, a designer becomes more confident in decisions to be done. Starting from a behavioral SystemC description different solutions are generated automatically by using software synthesis techniques and Forte Design Systems’ Cynthesizer for behavioral hardware synthesis. In order to allow such a degree of automation\, SystemCoDesigner requires the behavioral SystemC model to be representable in a well-defined Model of Computation\, called FunState. As a case study\, a model of a Motion-JPEG decoder was automatically optimized and implemented using SystemCoDesigner. Several synthesized SoC variants based on this model show different tradeoffs between required hardware costs and achieved system throughput\, ranging from software only solutions up to pure hardware implementations which reach real-time performance for QCIF streams on a 50MHz FPGA. In this talk\, the SystemCoDesigner overall design flow\, the FunState Model of Computation\, and some automatic transformation are presented using the Motion-JPEG case study.\n\n\n\n\n\n\n\n\n\n\nBiography\n\n\n\n\nChristian Haubelt received his diploma degree in Electrical Engineering from the University of Paderborn\, Germany\, in 2001. He received his Ph.D. in Computer Science from the University of Erlangen-Nuremberg\, Germany\, in 2005. Since 2004\, he is head of the System-Level Design Automation Group at the Chair of Hardware/Software Co-Design\, University of Erlangen-Nuremberg\, Germany. Dr. Haubelt’s research interests include electronic system level design\, system level design automation\, and multi-objective optimization.\n\n\n\n\n\n\n\n\n\n\nWeb Site\n\n\nhttp://www12.informatik.uni-erlangen.de/people/haubelt/

SUMMARY:Kilo-Instruction Processors: Overcoming the Memory Wall
DESCRIPTION:Kilo-Instruction Processors: Overcoming the Memory Wall\n\n\n\n\nSpeaker\n\n\nProfessor Mateo Valero\nComputer Architecture Dep. of the Polytechnical University of Catalunia\nCatalunia\, Spain\n\n\n\n\n\n\n\n\n\n\nLocation\n\n\nComputer Science 432\n\n\n\n\n\n\n\n\n\n\nDate & Time\n\n\nFebruary 16\, 2006\nRefreshments at 10:30am\, followed by Lecture\n\n\n\n\n\n\n\n\n\n\nAbstract\n\n\nToday’s systems have a very large and growing gap between processor and (DRAM) memory speeds\, which results in very long memory latency and loss of performance. Many different techniques have been proposed to address this problem: cache memories\, prefetching and other latency hiding techniques\, and multithreading\, to name a few. We proposed a different approach to solving this problem: a new type of out-of-order superscalar processor called the Kilo-Instruction Processor. Our design can have thousands of in-flight instructions using a scalable multi-check pointing mechanism. This allows memory access to be overlapped with the execution of a large number of other instructions and significantly improves performance. Kilo-Instruction Processors also offer advantages in multiprocessor systems\, where the average memory latency is even longer. They enable implementation of other very desirable features via their check-pointing mechanism. For example\, we can implement a multiprocessor transactional memory in hardware using checkpoints\, which enables an effective implementation of sequential consistency. This talk will describe the main ideas of our work on Kilo-instruction processors\, efficient\nimplementation options for this type of processors\, and their use in the design of multiprocessor systems.\n\n\n\n\n\n\n\n\n\n\nBiography\n\n\n  \n\nMateo Valero obtained his PhD at UPC in 1980.

SUMMARY:Cutpoints for Formal Equivalence Verification of Embedded Software
DESCRIPTION:Cutpoints for Formal Equivalence Verification of Embedded Software\n\n\n\n\nSpeaker\n\n\nDr. Alan Hu\nDepartment of Computer Science\nUniversity of British Colombia\n\n\n\n\n\n\n\n\n\n\nLocation\n\n\nIERF Conference Room 432\n\n\n\n\n\n\n\n\n\n\nDate & Time\n\n\nJune 17 \, 2005\nTalk begins at 9:30am\n\n\n\n\n\n\n\n\n\n\nAbstract\n\n\nLike hardware\, embedded software faces stringent design constraints\, undergoes extremely aggressive optimization\, and therefore has a similar need for verifying the functional equivalence of two versions of a design\, e.g.\, before and after an optimization. The concept of cutpoints was a breakthrough in the formal equivalence verification of combinational circuits and is the key enabling technology behind its successful commercialization. We introduce an analogous idea for formally verifying the equivalence of structurally similar\, “combinational” software\, i.e.\, software routines that compute a result and return/terminate\, rather than executing indefinitely. We have implemented a proof-of-concept cutpoint approach in our prototype verification tool for the TI C6x family of VLIW DSPs\, and our experiments show large improvements in runtime and memory usage.\n\n\n\n\n\n\n\n\n\n\nBiography\n\n\n  \n \nAlan Hu received his BS and PhD degrees from Stanford University . He is an associate professor and associate head of the Department of Computer Science at the University of British Columbia . For the past15 years\, his main research focus has been automated\, practical techniques for formal verification. He has served on the program committees of most major CAD and formal verification conferences\, and chaired or co-chaired CAV (1998)\, HLDVT (2003)\, and FMCAD (2004). He was also a Technical Working Group Key Contributor on the 2001 International Technology Roadmap for Semiconductors.

Fabrication variability imposes an underlying uncertainty on the design process of VLSI chips making several parameters random. Therefore\, the old way of doing design needs to be overhauled for considering this randomness. This implies that VLSI CAD needs to incorporate probabilistic models for capturing uncertainty and stochastic optimization for controlling the design decision variables. Several challenges need to be addressed before this is made possible…\n\n\n\n\n\n\n\n\n\n\nBiography\n\n\n  \n\nAnkur Srivastava received the B.S. degree from the Indian Institute of Technology\, Delhi\, the M.S. degree from Northwestern University\, Evanston\, IL\, and the Ph.D. degree from the University of California Los Angeles (UCLA) in 1998\, 2000\, and 2002.

SUMMARY:Practical Considerations for Power-Aware Real-Time Scheduling
DESCRIPTION:Continuous Compilation for Aggressive and Adaptive\nCode Transformation\n\n\n\n\nSpeaker\n\n\nDr. Bruce Childers\nDepartment of Computer Science\nUniversity of Pittsburgh\n\n\n\n\n\n\n\n\n\n\nLocation\n\n\nIERF Conference Room 127\n\n\n\n\n\n\n\n\n\n\nDate & Time\n\n\nMay 13 \, 2005\nRefreshments at 2:30pm\, Lecture begins at 3:00pm\n\n\n\n\n\n\n\n\n\n\nAbstract\n\n\nOver the past several decades\, the compiler research community has developed a number of sophisticated and powerful algorithms for a variety of code improvements. Although there are still promising directions for particular aspects of code optimization\, research on optimizations is nearing the point of diminishing returns and other approaches are needed to achieve further performance improvements. Our research aims to address this challenge by investigating and developing an innovative framework and system for continuously and adaptively applying code improvements. Our system\, the Continuous Compiler ( CoCo )\, determines “optimization plans” at compile-time that describe the best way in which to apply both static and dynamic code transformations. The plans consider program and machine context\, interaction among optimizations\, and performance profit. Through such planning\, CoCo can tailor and adapt its decisions to more synergistically apply a whole suite of code transformations.  \nThis talk will describe the Continuous Compilation approach and present initial results. These results include novel analytic models that can accurately predict the performance benefit (profit) of applying an optimization without actually doing it or running the resulting program code. Using the analytic models\, we have developed several planners that can guide a static optimizer. Initial results are very encouraging and show that optimizations can be effectively directed by planning. The talk will conclude with a brief discussion of CoCo ‘s run-time system\, including its dynamic code translator\, instrumentation optimizer\, and source-level debugger for dynamically translated code.\n\n\n\n\n\n\n\n\n\n\nBiography\n\n\n  \n \nBruce Childers is an Assistant Professor in the Department of Computer Science at the University of Pittsburgh.

His research interests are compilers and software development tools\, computer architecture\, and embedded systems. Current projects include continuous compilation to synergistically apply both static and dynamic code optimizations\, debugging for dynamically translated code\, power-aware real-time systems\, and demand-driven software testing.

Reduced time-to-market and low product cost requirements have been placing increased pressure upon designers to shift as much as possible of the system functionality onto a set of available microprocessor cores so as to reduce the hardware cost of the system and achieve faster time-to-market. Yet one of the fundamental difficulties in implementing larger parts of SOC functionality in software is the stringent timing constraints of the critical modules; methods need to be developed for matching such stringent constraints if embedded processor cores are to be widely used. Low-cost\, application-specific microarchitecture customizations promise to be an efficient solution to this problem. The basic advantage of microprocessor cores versus ASICs is the intrinsic reconfiguration capability of the processor by means of software. In order to preserve this fundamental advantage\, application-specific features added to the microarchitecture need to be implemented as reprogrammable hardware. Post-manufacturing customization capability can thus provide seamless migration to new applications possibly due to late specification changes or market requirements\, while delivering superior levels of performance. In this talk\, we outline the incorporation of application specific properties into the processor microarchitecture\, thus increasing performance and reducing power consumption. The fundamental approach is the identification of application properties during compile time and their dynamic exploitation during program execution by the processor. The basic characteristic of these properties is that their existence can be statically identifiable by the compiler\, and that they can lead to significant improvements in performance when exploiting their behavior dynamically. Such properties may consist of the control structure of the algorithm\, the run-time data values and the code manipulating some data structures; for example\, an array access\, its stride\, or its control structure. Microarchitectural features that can be enhanced with such application-specific information include the branch predictor\, the cache subsystem\, and the processor communication infrastructure; techniques aimed at all three are outlined in this talk.\ndownload pdf\n\n\n\n\n\n\n\n\n\n\nBiography\n\n\n  \n\nAlex Orailoglu received his BS Degree cum laude from Harvard University in Applied Mathematics and his M.S. and Ph.D. degrees in Computer Science from the University of Illinois \, Urbana-Champaign.

Unlike many other high-level synthesis tools\, MOODS optimizes designs by a series of small\, localized transforms to the data and control paths. This approach has some significant advantages over other techniques\, most notably that a number of different objectives can be specified\, without knowing the relationship between those objectives. Initially\, optimization was performed in terms of area and critical path delay\, but this has been extended (through a succession of PhD projects) to include power\, testability and reconfigurability. In this talk\, the techniques used and results achieved will be discussed\, together with future research directions.\n\n\n\n\n\n\n\n\n\n\nBiography\n\n\n  \n\nDr. Mark Zwolinski is a Reader (Associate Professor) in the School of\nElectronics and Computer Science at the University of Southampton UK. He\ncompleted his BS in Electronic Engineering and PhD in Electronics at\nthe University of Southampton\, too. He was appointed as a lecturer\n(Assistant Professor) in 1990. His PhD was on the topic of electronic\ncircuit simulation\, but he has since developed research interests in\nanalog and mixed-signal test\, high-level synthesis and verification. He\nhas published over 100 refereed conference and journal papers and is the\nauthor of two books.
