摘要/Abstract

摘要： 针对多媒体处理算法存储访问的特点，提出了一种新的多媒体扩展存储体系。该体系采用二维字节寻址，支持行访问和列访问；将数据置换操作与存储器访问操作相融合，通过数据置换来实现复杂的地址变换。基于此体系设计了指令系统和硬件原型。通过H.264算法测试表明，所述体系可以减少平均约32.0%的存储器访问率以及25.4%的时钟周期数。

Abstract: To satisfy rigid performance specifications of accessing to memory of multimedia processing，a novel multimedia memory architecture is proposed in this paper.The architecture is based on 2 dimensional addressing and support access modes such as row and column.Data permutation is merged with load/store operations to realize complex addresses transforming.The instruction set and hardware prototype are designed for the architecture.H.264 algorithm is used for benchmarking.Experiment results show that the 32.0% memory access times and 25.4% clock cycles can be reduced on the average.
