摘要 面向特定应用扩展指令集,并通过定制的硬件实现这些扩展指令,能够大幅度提高嵌入式处理器的性能.本文提出了一种全自动的面向特定应用的指令集扩展流程,该流程能够较精确地估算扩展指令的性能加速比和硬件开销,并高效完成指令模板匹配.实验结果表明,在给定的硬件开销限制下,该方法产生的扩展指令能够显著提升嵌入式应用的性能. Application-specific instructions play an important role in reducing code size and improving performance for em- bedded processors.Automating the design process of these instructions can shorten the time-to-market of the product. This paper pro- poses a fully automatic approach on instruction-set extension for embedded applications and a new algorithm for instruction pattem mapping. Experimental results show great performance improvement on various embedded applications under given hardware constraints.
