Abstract

Abstract. Current processors are based on a multithreaded architecture. Simultaneous Multithreading (SMT) techniques are used to increase instruction throughput under a multiprogramming workload; however, it does not improve performance when only a single thread is executing. This communication explores Speculative Precomputation, a technique that uses idle thread contexts in a multithreaded architecture to improve the performance of singlethreaded applications. It reduces program stalls, generated by data cache misses, using available thread contexts to prefetch these data. Speculative Precomputation tasks are described, and the examination of basic triggers and chaining triggers are made, using a Intel Itanium ISA processor as the evaluation base. 1
