| 摘 要： | 现有定制功能单元生成算法既没有考虑发射架构的配置情况,也没有考虑关键路径的改变,因此在面对多发射架构处理器时,其性能提高效果有限.该文基于有向无环图,通过分析对比特定配置下备选节点对应用的多方面影响,使用逐点生长的方法,提出了一种新的面向多发射架构特定应用指令集处理器(ASIP)的定制功能单元自动生成算法.结合3种不同...

| Abstract: | Current customized function unit(CFU) design algorithms do not consider the multi-issue architecture of the target processor so they may change the application critical path which limits performance improvements.This study uses a directed acyclic graph in an automatic generation design approach for CFU for a multi-issue application-special instruction set processor(ASIP),in which the CFU grows by analyzing several aspects of the impact of each candidate node on the application.Tests indicate that the speedu... |
