摘要
大量的多媒体信息处理是现代通用处理器面临的一个现实问题,本文在对通用处理器中的多媒体扩展进行简单的回顾之后,对多媒体的特征进行了分析,得出了现有通用处理器中多媒体扩展的共同特征,然后对现有多媒体扩展指令集进行了分类介绍,研究了在通用处理器中进行多媒体功能扩展的发展特点,最后,指出发展多线程或超线程多媒体处理器将是通用处理器发展的必然趋势。
It is a reality that general processors encounter a mass of multimedia workloads. After giving an overview of the multimedia extensions in general processors,characteristics of multimedia processing are analyzed and common feature is given in this paper. Classes of instructions for multimedia extensions are introduced and the developing features in the multimedia extensions for the general processors are also studied in this paper. In the end the authors point out that it will be a heritable trend to develop multithreaded or superthreaded multimedia processors for general-purpose processors.
