Question

The $3$ bit operation code for ADD operation is $001$ and indirect memory address is $23$ then $16$-bit instruction code can be written as-

• A. $00001000000010111$
• B. $1001000000010111$
• C. $100010000000010111$
• D. None of the above

Answer 1

The correct option is A $00001000000010111$

The 3-bit operation code for ADD operation is 001 and the indirect memory address is 23 then 16-bit instruction code can be written as 00001000000010111.

Indirect memory address:-

The effective address of the operand is the contents of a register or main memory location, location whose address appears in the instruction. Indirection is noted by placing the name of the register or the memory address given in the instruction in parentheses.
