Performance Evaluation of SMT and CMP Processor Using Super Scalar Simulator

Abstract- Multithreading and prefetching are the techniques used to increase the performance of the processor. Multithreading executes another concurrent thread when running thread encounters a catch miss. Prefetching increases the single thread performance by predicting the data address in advance. This paper presents the performance of standard benchmarks in simultaneous multithreading processor (SMT) and chip multiprocessor (CMP). SMT is a tightly coupled system where the processor and the cache are dependent on each other. CMP is a loosely coupled system with independent processor and cache. The processor is demonstrated by cyclic accurate execution driven simulator and the processor performance are evaluated based on execution speed and execution time
