RISC Approach - computer architecture:

The RISC processors only use easy instructions that can be executed within one clock cycle. therefore, the "MULT" command discussed above could be divided into three separate commands: 1)"LOAD," which  is used to moves data from the memory bank to a register, 2) "PROD," which is used to finds the product of two operands located within the registers, and  3) "STORE," which is used  moves data from a register to the memory banks. In order to perform the precise series of steps described in the CISC approach, a programmer would require coding 4 lines of assembly:

LOAD A, 2:3

LOAD B, 5:2

PROD A, B

STORE 2:3, A

Firstly, it may seem like a much less competent way of completing the operation. Because there are more lines of code so more RAM is required to store the assembly level instructions. The compiler ought to be performing more work to convert a high-level language statement into the code of this form.
