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 is a realization of a 64-bit MIPS III instruction set of general-purpose RISC processor. Godson-2E line instructions per clock cycle for decoding from the four directions, and dynamically launched into the five-wide features of water. Although the Directive to ensure dependent on the premise that the relationship between out-of-order execution, but the instructions to submit the original or order in accordance with the procedures to ensure accurate order of suspension and keep the implementation of the visit.
