Hi Guys,
In most of the books it is mentioned that PC contains the starting address of instruction.
And during the fetch cycle it is incremented and it points to the next instruction. is this always TRUE ?
But I have one doubt -
Let us assume we have One Word, Two Word and Three Word instructions in our computer then before ID(instruction decode) phase how do we know how much PC should be incremented because in IF phase we do not know - how many words does current instruction take ?
