为了提高性能,传统的CISC处理器正在采用RISC某些特性.这类CISC处理器包括历史悠久的x86系列和用于嵌入式控制的各种处理器.这些处理器现在加入了全RISC结构的CPU行列,其性能高达数百MIPS.上个月在加州Burlingame举行了微处理器研讨会.得克萨斯州Austin的Advanced Micro Devices(AMD)公司和加利福尼亚州Milpitas的NexGen公司在会上介绍了它们研制的Intel Pentium兼容型微处理器.这些芯片的核心均是RISC CPU,运行自已独有的RISC指令系统.虽然从外部表现来看它们是在执行x86指令系统,但其性能比相同时钟频率的Pentium处理器高出30%.
In order to improve performance, traditional CISC processors are taking advantage of certain features of RISC such CISC processors include the historic x86 family and various processors for embedded control.These processors are now integrated into the CPU of a full RISC architecture With performance up to hundreds of MIPS. A microprocessing seminar was held in Burlingame, Calif., Last month. Advanced Micro Devices (AMD) of Austin, Texas, and NexGen of Milpitas, California introduced their Intel Pentium-compatible microprocessor.The core of these chips are RISC CPU, run their own unique RISC instruction set.Although they are from the external performance of the x86 instruction set, but its performance than the same clock frequency Pentium processor 30% higher.
