| Abstract: |
Even though the beginnings of microprogramming date hack to the early 1950s, we still see extensive use of microprogramming today. This article has given one complete example of how microprogramming is used to control a CPU datapath. In many CPUs developed today, microcode has been replaced with hardwired control logic. Many of the same principles apply to hardwired control, which are fundamental to the design of microprograms, because both are variations of a finite state machine (one developed in hardware, another developed in software and supporting control logic). The major application of microprogramming is seen in the microcontroller world. These simple CPUs are used to control a variety of electrical and mechanical devices. Microprogramming is used to control these devices. Other discussion of microcoding and microprogramming can be found in Refs. 7-10, We refer the reader to these recognized textbooks for further information on this topic. [ABSTRACT FROM AUTHOR] |
