Question

What is actually done to improve the efficiency of a RISC processor?

(a) instructions are reduced

(b) they have two or more processors inbuilt connected between

(c) they have many instructions that are interrelated to each other

(d) they have one or more registers hard wired to the commonly used values

I had been asked this question by my school teacher while I was bunking the class.

This interesting question is from Architecture in division MSP430 Microcontroller of Microcontroller

Answer 1

Correct choice is (d) they have one or more registers hard wired to the commonly used values

The best I can explain: To improve the efficiency of the RISC processor, the registers that are hard wired to commonly used values are used instead of other ones.
