5.微程序方式计算机的实例由前几章,我们基本掌握了微程序设计的基本知识,这一章我们讲述微程序方式计算机的实例。5.1 计算机的扩充为了讨论实际计算机,我们在前面讲的计算机的被控制部分增设一些寄存器,并把遥算及其执行顺序作一整理以提高效率。对前几章讲解所使用的计算机框图,在R总线上增设称为B、Q、F的寄存器,在S总线上增设称为S1、S2、S3、S4的寄存器,如图5—1所示。

5. Microprogram mode computer examples From the previous chapters, we have a basic grasp of the basic knowledge of micro-programming, this chapter we talk about micro-computer program instance. 5.1 Computer Expansion To discuss the actual computer, we added some registers to the controlled part of the computer we talked about above and arranged the remote arithmetic and its execution order to improve efficiency. Explained to the previous chapters of the computer block diagram used in the R bus additional registers called B, Q, F, in the S bus additional called S1, S2, S3, S4 registers, as shown in Figure 5-1 .
