Abstract

In this issue, we present the papers from the proceedings of the 2nd International Workshop on Advanced Low Power Systems (ALPS 2007) that was held in conjunction with the 21st International Conference on Supercomputing in Seattle.
"Thoughtfulness" is an important keyword in the both current and future technologies in all over the world: Thoughtful to human being, thoughtful to our surroundings, thoughtful to the earth, and so on. For the thoughtfulness, Low-power is believed to be one of the most indispensable keyword. The ALPS workshop focuses on the current technological challenges in developing low-power and power-aware computing systems ranging from servers to embedded devices. The goal of the workshop is to bring all aspects of power-aware computing from industry and academia.
This year, we have one invited talk entitled "An Under 2W 100GOPS Video Recognition Processor Based on a Linear Array of 128 4-Way VLIW Processing Elements" by Shorin Kyo (NEC Corporation) and 6 papers selected based on the full paper review by the program committee members.
The first set of papers discusses low-power designs. We have three papers: "Optimal Pipeline Depth with Pipeline Stage Unification Adoption" by Jun Yao, Hajime Shimada, Shinobu Miwa, and Shinji Tomita, "VCLEARIT: A VLSI CMOS Circuit Leakage Reduction Technique For Nanoscale Technologies" by Preetham Lakshmikanthan and Adrian Nunez, and "Leakage Energy Reduction in Cache Memory by Data Compression" by Kiyofumi Tanaka and Takahiro Kawahara.
The second set of papers: "Preventing Timing Errors on Register Writes: Mechanisms of Detections and Recoveries" by Hidetsugu Irie, Ken Sugimoto, Masahiro Goshima, and Suichi Sakai, "Not Multi-, but Many-Core: Designing Integral Parallel Architectures for Embedded Computation" by Mihaela Malita, Gheorghe Stefany, and Dominique Thiebaut, and "Fine-grain Compensation Method with Consideration of Trade-offs between Computation and Data Transfer for Power Consumption" by Takefumi Miyoshi and Nobuhiko Sugino, covers reliability, many-core and parallelization issues.
All papers here are going to create the way to the new aspects of low-power systems. We hope you will find the papers of this special issue of Computer Architecture News to be stimulating and that you will be inspired to contribute your efforts to the future low power systems.
