HI!
In our lecture on microprocessor, the fetch cycle goes like this:
Fetch1: AR <- PC
Fetch2: DR <- Mem, PC <- PC + 1
Fetch3: IR <- DR, AR <- PC
Is it possible to reduce the fetch cycle into 2 states or 1 state?
I am thinking of removing the Address Register and tapping the Program counter directly into the memory. Is that possible?
