Answer -
RISC processors only use simple instructions that can be executed within one clock cycle. Thus, the “MULT” command could be divided into three separate commands: “LOAD,” which moves data from the memory bank to a register, “PROD,” which finds the product of two operands located within the registers, and “STORE,” which moves data from a register to the memory banks. In order to perform the exact series of steps described in the CISC approach, a programmer would need to code four lines of assembly :
LOAD A, 2 : 3 LOAD B, 5 : 2
PROD A, B STORE 2:3, A
