Description
We make a comparative evaluation or the memory accesses or vector and superscalar processor whose memory accesses are pipelined. In this evaluation, we assume that the configuration or arithmetic units and main memory are the same, and used the most suitable code for each architecture by applying optimizations like loop unrolling. We have round that vector processor achieves higher performance in multiply-add accumulation because or sequential memory access. On the other hand, for inner product, both processors perform stride accesses. Despite the disadvantage or the superscalar processor on multiply-add accumulation, given that both architectures yield similar performances, we conclude that the superscalar processor is general purpose.
