CISC Approach - CISC architecture:

The main goal of CISC architecture is to finish a task in as few lines of assembly as possible as. This is gain by building processor hardware that is able to understand and execute a series of operations. For this specific task, a CISC processor would come prepared with a individual instruction (we'll call it "MULT"). When this instruction is executed, it loads the two values into distant registers, multiplies the operands in the execution unit, and then holds the product in the proper register. Thus, the all task of multiplying two numbers can be completed with only one instruction:

                                                         MULT 2:3, 5:2

MULT which is known as a "complex instruction." It directly operates on the computer's memory banks and does not need the programmer to explicitly call any loading or storing functions. It nearly resembles a command in a higher level language. For an example, if we let "a" stand for 2:3 and "b" stand for 5:2, then this command is identical to the C statement "a = a * b."

One of the main advantages of this system is that the compiler has to do very small work to translate a high- level language statement into assembly language. Because the length of the code is relatively small, very little RAM is needed to store instructions. The emphasis is put on building difficult instructions directly into the hardware.
