Mohammad Ali Ghodrat, Tony Givargis, and Alex Nicolau recently received the Best Paper Award for CASES 2008 for their “Control Flow Optimization in Loops Using Interval Analysis.” Congratulations!
Abstract of Paper:
The work presents a novel loop transformation technique, particularly well suited for optimizing embedded compilers, where an increase in compilation time is acceptable in exchange for significant performance increase. The transformation technique optimizes loops containing nested conditional blocks. Specifically, the transformation takes advantage of the fact that the Boolean value of the conditional expression, determining the true/false paths, can be statically analyzed using a novel interval analysis technique that can evaluate conditional expressions in the general polynomial form. Results from interval analysis combined with loop dependency information is used to partition the iteration space of the nested loop. In such cases, the loop nest is decomposed such as to eliminate the conditional test, thus substantially reducing the execution time. Our technique completely eliminates the conditional from the loops (unlike previous techniques) thus further facilitating the application of other optimizations and improving the overall speedup. Applying the proposed transformation technique on loop kernels taken from Mediabench, SPEC- 2000, mpeg4, qsdpcm and gimp, on average we measured a 175% (1.75X) improvement of execution time when running on a SPARC processor, a 336% (4.36X) improvement of execution time when running on an Intel Core Duo processor and a 198.9% (2.98X) improvement of execution time when running on a PowerPC G5 processor. The CASES conference provides a forum for emerging technology in embedded computing systems, with an emphasis on compilers and architectures for embedded systems. CASES is a common forum for researchers with an interest in embedded systems to reach across vertically integrated communities and to promote synergies. As evident from the past CASES meetings, several emerging applications are critically dependent on these interactions for their sustained growth and evolution (from http:// thedude.cc.gt.atl.ga.us/conferences/cases/).

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.
Automatic 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.
In 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.
CECS congratulates the researchers on their achievement and wishes them success in their future endeavors.

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).
This 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.
Currently, 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.

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.
Heydari 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.
The 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.
It 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.
In 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.
The 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.

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."
The 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.
In 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.
FPL 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.
