In recent years, a lot of computer simulation codes have been developed as open-source software. Meanwhile major processors adopt a concept of a vector processing in high performance computing. Hence, the computer simulation codes need to follow a vector processing manner to have a benefit of a computational potential of the vector processing. Our study is evaluation and analysis of performance of...
The cost of maintaining an application code would significantly increase if the application code is branched into multiple versions, each of which is optimized for a different architecture. In this work, default and vector versions of a realworld application code are refactored to be a single version, and the differences between the versions are expressed as userdefined code transformations. As a...
It is a pleasure for me to welcome you to the COOL Chips 20, the 20th anniversary of the IEEE Symposium on Low-Power and High-Speed Chips. COOL Chips Conference Series started in 1998, which was held in Tokyo as a one-day event of invited talks only. Now COOL Chips is a three-day event fully sponsored by IEEE Computer Society, which covers not only the chip architecture design, but also software technologies...
Nowadays, multimedia applications (MMAs) form an important workload for general purpose processors. Although the vector architecture is considered the most potential candidate for media processing, the traditional vector architecture has inefficiencies to execute MMAs. This paper proposes a media-oriented vector architecture, which improves the traditional one with a load-forwarding mechanism. The...
