CISC :- CISC stands for complex instruction set computer.
RISC :- RISC stands for reduced instruction set computer.
Sr. No. | CISC | RISC |
---|---|---|
1. | Complex instruction set computer | Reduced instruction set computer |
2. | It has large number of instruction | It has small number of instruction of fixed length |
3. | Complex instruction take multiple clock cycle | Single cycle instruction |
4. | Complex & variable length instruction | Simple length instruction |
5. | Less register are used | More register are used |
6. | Compound addressing mode | Limited addressing mode |
7. | Required a minimum amount of RAM | Required more RAM |
8. | Instructions are executed by microprogram | Instructions are executed by hardware |
9. | Pipelining is difficult | Pipelining is easy |
10. | Example : PIC microcontroller from microchip, ARM, Power PC etc. | Example : 8085, 8086, 8051 etc. |
