Question

Computer Architecture

1.

You are designing a single-chip computer for an embedded system. The chip is going to have all its memory on the chip and running at the same speed as the CPU with no access penalty. Assuming that high performance is still desired, the following Design Principle is still important.

All instructions are directly executed by hardware.

true or false?

2.

Maximize the rate at which instructions are issued.

You are designing a single-chip computer for an embedded system. The chip is going to have all its memory on the chip and running at the same speed as the CPU with no access penalty. Assuming that high performance is still desired, the following Design Principle is still important.

Only loads and stores should reference memory.

true or false?

You are designing a single-chip computer for an embedded system. The chip is going to have all its memory on the chip and running at the same speed as the CPU with no access penalty. Assuming that high performance is still desired, the following Design Principle is still important.

Provide many registers.

true or false?

Answer 1

ANSWER -

There is a set of design principle which is called as reduced instruction set computer (RISC)

1. TRUE

To eliminate level of interpretation, instruction should be executed by hardware.

2. TRUE

As the high performance is the priority, instruction should be issued at maximum rate

3. TRUE

The aim is to produce a high performance single-chip computer, for that instructions should be easy to decode.

4. FALSE

This is not necessary because the chip has all the memory on the chip itself.

5. FALSE

As the chip will run at same speed as that of CPU and the memory is in the chip itself, this principle is not important.
