Abstract

An effective design method for VLSI-based microprocessors is proposed. The chip is divided into three components, namely control logic, data paths, and macrocells, at a very early stage. The control logic is automatically designed by logic synthesis and automatic placement and routing. For the data paths and the macrocells, logic and layout are designed manually. By combining the design method with so-called design-pipelining, a 32-bit microprocessor with 460 K transistors was designed in a year without sacrificing the chip size and performance. The method's impact on design effort is also discussed

全定制微处理器的优化设计方法

提出了一种有效的vlsi微处理器设计方法。该芯片在非常早期的阶段分为三个部分，即控制逻辑、数据路径和宏单元。控制逻辑采用逻辑综合自动设计，自动布放布线。对于数据路径和宏单元格，逻辑和布局是手动设计的。通过将设计方法与所谓的设计流水线相结合，在不牺牲芯片尺寸和性能的情况下，在一年内设计出了具有460 K晶体管的32位微处理器。讨论了该方法对设计效果的影响
