Analysing a multistreamed superscalar speculative instruction fetch mechanism

Abstract

This work presents a new model for multistream speculative instruction fetch in superscalar architectures. The performance evaluation of a superscalar architecture with this feature is presented in order to validate the model and to compare its performance with a real superscalar architecture. This model intends to eliminate the instruction fetch latency introduced by branch instructions in superscalar pipelines. Finally, some considerations about the model are presented as well as suggestions and remarks to future works.
