Question

The current value of the PC is 00000000 16, can you use a single jump instruction to get to T?

Options:
a) JUMP T
b) JUMP IF ZERO T
c) JUMP IF NOT ZERO T
d) JUMP IF NEGATIVE T

Answer 1

The correct answer is option b) JUMP IF ZERO T. The JUMP IF ZERO instruction can be used to reach T when the current value of the PC is zero.

The correct answer is option b) JUMP IF ZERO T. In the given question, the current value of the PC (Program Counter) is represented as 00000000 16. The PC stores the address of the instruction being executed in a computer program. A jump instruction allows the program to change the value of the PC and transfer control to a different part of the program. When the PC is 00000000 16, it means that the value is zero. The JUMP IF ZERO instruction checks if the zero flag is set and if it is, it jumps to the address labeled as T. Since the current value of the PC is zero, the JUMP IF ZERO T instruction would be able to reach T.
