Sr No. | CISC | RISC |
---|---|---|
1. | CISC is known as Complex instruction set computers. | RISC is known as reduced instruction set computers. |
2. | Addressing modes are complex. | Addressing modes are reduced in RISC processors. |
3. | These processors have Variable length instructions | Fixed length instructions. |
4. | High power consumption as compared to RISC processors. | Power consumption is low comparatively. |
5. | Less number of registers. | RISC has large number of instructions. |
6. | Pipeline in CISC processors maybe a little complex. | These processors has simple pipeline. |
7. | These processors doesn’t fall in load store architecture. | RISC processors follows load-store architecture. |
8. | Microprogrammed control logic. | Hardwired control logic. It is comparatively faster than microprogrammed control unit. |
