OpenRisc是OpenCores组织提供的基于GPL协议的开放源代码的RISC（精简指令集计算机）处理器。有人认为其性能介于ARM7和ARM9之间，适合一般的嵌入式系统使用。最重要的一点是OpenCores组织提供了大量的开放源代码IP核供研究人员使用，因此对于一般的开发单位具有很大的吸引力。-OpenRisc is based organizations OpenCores the GPL open source RISC (Reduced Instruction Set Computer) processor. Some people think that the performance between the ARM7 and ARM9, an embedded system for general use. The most important point is OpenCores organization provides a number of open-source IP cores for researchers to use, so for the average developer is very attractive.
