Question

A digital computer has a memory unit with a capacity of 16348 units,40 bits per word.The instuction code format consists of six bits for the operation part and 14bits for the address part.Two instructions are packed in one memory word and a 40 bit instuction register IR is available in the control unit.Formulae a procedure for fetching and excuting instructions for this computer.

Answer 1

"You need to calculate it on your own but here are the few things that can help you out:

• if there are six bits for each operation instructions to be handled by the processor, you should make room for each one instruction, meaning six bits for every operation that will have unique instruction codes for them.

• Secondly, 40 - the above answer will give you the remaining bits

• Lastly, the total size would be rows * cols
