Computer architecture system :

Please let me know if you need more time. Thank you in advance.

Q: A. The following microoperations can't be executed during a single clock pulse in the system shown in Fig. 5-4. Specify the sequence of microoperations that will perform the operation. a MPC]– DR Single microoperation Sequence of microoperations O M[PC] DR Single microoperation AC - DR + M[AR] | Sequence of microoperations O Single microoperation AC, TR Sequence of microoperations O (d. | Single microoperation AC – MTAR ] | Sequence of microoperations O Single microoperation MARK – MAR]+1 Sequence of microoperations O S2 - Memory unit 4096 x 16 Write LD INR CLR LDINR CLR DR LD INR CLR LD INR CLR INPR IR LD INR CLR OUTR - Clock 16-bit common bus Figure 54 Basic computer registers connected to a common bus. From: Computer System Architecture-morris mano Third Edition

Explanation / Answer

1) M[PC]<-DR
F <- DR
MBR <- (MEMORY)
MBR <-F
M[PC]<-MBR

2) AC <- DR + M[AR]
MBR <-(MEMORY)
T <- AR
MBR <-T
AC=AC+MBR
AC=AC+DR

3) AC <- TR
F <-TR
AC <-F

4) AC <-M[AR]
MBR <- (MEMORY)
MBR <- AR
AC <- MBR

5) M[AR] <- M[AR]+1
MBR <- (MEMORY)
MBR <- AR
MBR <- MBR + 1
F <- MBR
