Research on X Processor's Memory Hierarchy

With the expanding area of computer application,stream media application and scientific computing are becoming an important kind of application of processor.Stream media applications are characterized by large amounts of available parallelism,little data reuse,and a high computation to memory access ratio.Because of limited global bandwidth,these characteristics are poorly matched to conventional microprocessor architectures.X processor is a stream architecture processor.The memory hierarchy of X processor which aims at releasing the problem of bandwidth of stream application efficiently is comprised of local register file,stream register file and off-chip DRAM.On the simulation platform,this paper implements two methods(RS Code and simulation procedure),it validates the efficiency of the stream memory hierarchy and proves the design.
