摘要

HaL PM1 CPU是64位SPARC Version 9指令集架构的第一个实现。该处理器利用超标量指令发出、寄存器重命名和执行的数据流模型。指令可以乱序完成,然后按顺序提交。PM1 CPU保持精确状态。该处理器的可靠性比目前商业市场上的台式计算机更高。

Microarchitecture of HaL's CPU
The HaL PM1 CPU is the first implementation of the 64-bit SPARC Version 9 instruction set architecture. The processor utilizes superscalar instruction issue, register renaming, and a dataflow model of execution. Instructions can complete out-of-order and are later committed in order. The PM1 CPU maintains precise state. The processor has a higher level of reliability than is currently available in desktop computers for the commercial marketplace.
