Instruction Pointer & Program Counter

:arrow:Whats the difference between instruction pointer and program counter:?: Posted in: #Coffee Room

program counter and instruction pointer both are same

it holds address of instruction currently being executed

ya program counter , instruction counter and location counter are same and it is a type of register which holds the location of current program being executed by holding its address and the contents of the program counter is transfered to the control unit basing on the MDR (Memory Data Register)instruction.

And the location counter transfer the control to the MAR(memory Address Register) , now it also contains the address of the current executed memory location and now MBR contains a copy of the content of memory which is specified by MAR(memory buffer register).

i think both r same.But program counter means register which holds the address of nxt instruction to be executed.
