摘要

本文采用投合预测器(Agree predictor)的设计思想扩展UNICORE体系结构

旨在评测转移预测器中各项配置对单发射流水线结构的性能影响

为UNICORE体系结构改进提供定量依据.实验基于系统级模拟器

综合转移预测策略和转移目标缓冲器行为进行完整模拟

结论对于其它采用单发射流水线结构的微处理器设计具有较好的借鉴意义.

Abstract

We introduced agree predictor into UNICORE architecture to evaluate the performance enhancement brought by the configuration of dynamic branch predictor

in order for giving quantitative reference for UNICORE reconstruction.Using system simulator

we synthetized the effect of the prediction scheme and the branch target buffer.The conclusion is useful to the single-issue-pipeline microprocessor design.
