摘要

preore方法允许从C语言自动生成特定于应用程序的微体系结构，从而支持在可重构计算机上的复杂推测执行。在这项工作中，我们提出了使用数据值推测来减少内存读取延迟的preore功能，以及静态数据路径控制器的轻量级扩展，以动态重播错误推测的操作。实验评估考虑了该方法的性能/区域影响，并讨论了组合不同投机机制的个体影响。

Evaluation of speculative execution techniques for high-level language to hardware compilation

The PreCoRe approach allows the automatic generation of application-specific microarchitectures from C, thus supporting complex speculative execution on reconfigurable computers. In this work, we present the PreCoRe capability of using data-value speculation to reduce the latency of memory reads, as well as the lightweight extension of static datapath controllers to the dynamic replay of misspeculated operations. The experimental evaluation considers the performance / area impact of the approach and also discusses the individual effects of combining different speculation mechanisms.
