Write CISC Approach.



Answer -

The primary goal of CISC architecture is to complete a task in as few lines of assembly aspossible. This is achieved by building processor hardware that is capable of understanding and executing a series of operations. For this particular task, a CISC processor would come prepared with a specific instruction (we’ll call it “MULT”). When executed, this instruction loads the two values into separate registers, multiplies the operands in the execution unit, and then stores the product in the appropriate register. Thus, the entire task of multiplying two numbers can be completed with one instruction : MULT 2:3, 5:2.
