摘要
PowerPC620是PowerPC系列中用于高档工作站和高速服务器的第一种芯片，它采用了许多先进的微结构。例如：采用了动态转移预测、推测执行、寄存器更名、保留站和高带宽总线接口等新的结构技术，以提高指令的并行性，使其能持续达到每个周期执行4条指令的速度。本文详细地介绍了PowerPC620的结构特点及其主要的性能。
Power PC 620 microprocessor is the first chip for the high -speed server and high-end workstation product line within the Power PC family. It employs many advanced microarchitectural techniques. For exampIe, dynamic branch prediction, speculative execution, register renaming, reservation stations, and maximum bus bandwidth are used to enhance instruction execution rate of 4 instruction per cycle. This paper will describe in detail architectural feature and primary performance of Power PC 620 microprocessor.
