| الوصف: | In this paper we investigate the behavior of data prefetching on an access decoupled machine and a superscalar machine. We assess if there are benefits to using the decoupling paradigm given that an out-oforder (o-o-o) superscalar architecture could in principle prefetch to the same degree as an access decoupled machine. We have found that for large issue width the access decoupled machine can hide memory latency more effectively than a single instruction window o-o-o superscalar architecture. Our findings also demonstrate that an access decoupled machine offers the benefit of reducing the complexity of window issue logic. 1 Introduction The future of high performance microprocessor design is to provide improved performance by extracting higher degrees of instruction level parallelism. In superscalar architectures parallelism is exploited by reordering instructions within an instruction window and issuing multiple independent instructions per cycle. However as processor speeds increa. |
