*Repeat Problem for the CISC instruction, Memory Scalar Add. This instruction uses the contents of R[SB] as the vector length. It adds the elements of the vector with its least significant element in memory pointed to by R[SA] and places the result in the memory location pointed to by R[DR].
Problem
Write microcode for the execution part of each of the following CISC instructions. Give both a register transfer description and binary or hexadecimal representations similar to those shown in Table for the binary code for each microinstruction.
