Question

Which of the following components is not a part of an instruction format in CPU processing?

• A. Source operand
• B. Register file
• C. Destination operand
• D. Opcode

Hint:

Instruction formats include the opcode and operands (source and destination), but the register file is a separate part of the CPU architecture.

Answer 1

The Correct Option is B

In CPU instruction formats, the main components typically include:
The Opcode (to specify the operation),
Source operand(s) (specifies the input data),
Destination operand (specifies where the result is stored).
The register file is not part of the instruction format itself, but rather a part of the CPU's internal structure used for storing the values of registers.
Thus, the correct answer is: \[ \boxed{{Register file}}. \]
