Question

Consider the following processor design characteristics:

I. Register-to-register arithmetic operations only.

II. Fixed-length instruction format.

III. Hardwired control unit.

Which of the characteristics above are used in the design of a RISC processor?

Answer 1

RISC processor characteristics:

1. It supports more registers, so ALU operations are performed only on a register data.

2. It support fixed length instructions.

3. It uses hard-wired control unit.
