A two-word in...

Question

A two-word instruction is stored in memory at an address designated by the symbol w. The address field of the instruction (stored at w + 1) is designated by the symbol Y. The operand used during the execution of the instruction is stored at an address symbolized by 7.

Which of the following relation is true for direct addressing mode?

Solution

option (c)

The given scenario can be represented graphically a follows :

In direct addressing mode, address field of instruction contains the effective address ( address of operand).

hence given value Y is equal to Z.

Q. Consider a three word machine instruction

A D D A [R_{0}], @ B

The first operand (destination) "

A [R_{0}]

" uses indexed addressing mode with

R_{0}

as the index register. The second operand (source) "@B" uses indirect addressing mode. A and B are memory addresses residing at the second and the third words, respectively. The first word of the instruction specifies the opcode, the index register designation and the source and destination addressing modes.
