Difference between RISC Processor and CISC Processor:

The difference between RISC Processor and CISC Processor is given in table below

RISC Processor

CISC Processor

In RISC processor, emphasis is given on software. In CISC processor, emphasis is given on hardware.
In RISC processor, Reduced and simple instructions are used. In CISC processor, Large number of instructions including complex instructions are used.
In RISC processor, Each instruction is executed within a single clock. In CISC processor, Multi-clocks are required to execute complex instructions.
For register-to-register data movement, LOAD and STORE instructions are independently operated. For memory-to-memory data movement, LOAD and STORE instructions are incorporated in instructions.
There are large code sizes for a program, but the number of cycles per instruction is low. It has small code sizes for a program, but the number of cycles per instruction is high.
RISC processor spends more transistors on memory registers. Transistors are used for storing complex instructions.
