Abstract: Cache technique which is popular in general processor has been introduced to embedded processors to improve its performance. Usinga simulation based method, this paper studies several basic cache structure parameters under embedded environment.Parameters involved includeblock size, cache size and associativity. During the analysis, this paper also takes into account the influence of main memory implementation
