For computers based on three-address instruction formats, each address field can be used to specify which of the following:
-
(S1) A memory operand
(S2) A processor register
(S3) An implied accumulator register
Correct Answer: A
Question 21 Explanation:
Any implied register is never explicitly mentioned as an operand in an operation.
So as the question asks what can be specified using the address fields, implied accumulator register can’t be represented in address field.
So, S3 is wrong.
Hence Option A is the correct answer.

Hence Option A is the correct answer.
Either S1 or S2
Either S2 or S3
Only S2 and S3
