目前，多媒体应用程序（mma）已成为通用处理器的重要工作负载。虽然矢量体系结构被认为是媒体处理最有潜力的候选者，但传统的矢量体系结构在执行mma时效率低下。本文提出了一种面向媒体的矢量体系结构，在传统的矢量体系结构基础上增加了负载转发机制。负载转发机制克服了内存带宽利用率低的缺点。结果表明，该体系结构在硬件成本较低的情况下实现了更高的性能。本文用体系结构设计参数对所提出的体系结构进行了评估，并找出了矢量体系结构在执行mma时最有效的尺寸。
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 load-forwarding mechanism overcomes the inefficiency on utilization of the memory bandwidth. As a result, the proposed architecture achieves a higher performance with lower hardware cost than the traditional one. This paper evaluates the proposed architecture with architectural design parameters and finds out the most efficient size for the vector architecture when performing MMAs.
