In order to achieve a low energy execution for any multimedia applications (MMAs) on a vector processing mechanism (VPM), the number of parallel arithmetic pipelines and the number of cache ports of VPM must be properly configured for each MMAs. Therefore, this paper proposes an energy optimization method for VPMs (EOM-VP), which finds the lowest energy configuration by using the greedy searching...
Although modern SIMD extensions enable to improve the performance of MMAs, the limited parallel-processing capability and low memory bandwidth are their drawbacks to execute next generation MMAs. This paper proposes a novel media-oriented vector architectural extension (MVPX) to aim at accelerating a wide range of next generation MMAs. MVPX consists of an out-of-order vector processing mechanism (OVPM)...
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...
