龙芯2E处理器用户手册 中国科学院计算技术研究所 意法半导体公司 2006年 9 月

龙芯2E处理器是一款实现64位MIPS III 指令集的通用RISC处理器。龙芯2E的指

令流水线每个时钟周期取四条指令进行译码，并且动态地发射到五个全流水的功能部件

中。虽然指令在保证依赖关系的前提下进行乱序执行，但是指令的提交还是按照程序原

来的顺序，以保证精确中断和访存顺序执行。 -Godson 2E processor user manual CAS Institute of Computing Technology agreed that the semiconductor companies in 2006 9 Godson 2 on E processor is one realization of 64 MIPS Instruction Set III generic RISC processor. Godson 2 E. pipelined instructions every clock cycle from four decoding instructions, Dynamic and fired five full pipeline of functional components. Although the directive in ensuring dependence carried out under the premise of Out-of-order execution, However, the directive is to follow the procedures of the original order to ensure accurate and interrupted his visit to the implementation of the order deposit.
