继 1999年底研制出我国第一颗具有自主知识产权的嵌入式微处理器后，北京大学最近又成功研制出支持 32位和 16位两套指令系统的微处理器，并设计出操作系统和信息家电的原型。这标志着我国嵌入式微处理器的研制达到 90年代末国际水平。这套系统不仅具有较高的性能，而且功耗也 Following the development of China’s first embedded microprocessor with independent intellectual property rights by the end of 1999, Peking University recently successfully developed a microprocessor that supports both 32-bit and 16-bit instruction sets and designed an operating system and information appliances Prototype. This marks the development of China’s embedded microprocessor reached the international standards of the late 90s. This system not only has high performance, but also power consumption
