单周期8位微控制器的时序及流水线设计

Timing and pipeline technology of a novel single-cycle 8-bit microcontroller

分析传统8051微控制器的时序设计可以发现,在12个时钟周期的机器周期架构中存在着巨大的浪费,多数指令被强制去执行哑周期.利用并行技术及流水线技术设计了一个全新的单周期8位微控制器,并详细设计了单周期实现时序及两级流水线技术,最后与传统8位微控制器进行了计算性能对比,可以看出其执行速度比标准8051平均提高10倍左右.

By analyzing the characteristic of traditional 8051 microcontroller, we found that there are great time wastes on twelve cycle architecture. In order to improve the 8-hit microcontroller＇s performance, we design and implement a one-cycle 8-hit microcontroller, using parallel technology and pipeline technology. This paper described the time sequence of one cycle architecture and its two stage pipeline technology in detail. Compared with traditional 8-hit microcontroller, the new one cycle architecture＇s speed of operation is about ten times more than traditional 8-hit architecture.
