Question

How to fetch a word from Memory

Answer 1

Answer:

Explanation:

CPU transfers the address of the needed information word to the memory address register (MAR). Address of the needed word is transferred to the primary memory. In the meantime, the CPU uses the control lines of the memory bus to mention that a read operation is needed.

Answer 2

Explanation:

Data is generally transferred between registers in the CPU and memory cells. When you want to fetch a word from the memory, it depends on the implementation of that particular process architecture.

After your fetch the word you need to decode.

For example when you input is 2 words which is of a fixed length, you can fetch two words from the memory instead of one in a fetch cycle.
