A two word instruction is stored at memory addresses 200 and 201. The first word of the
instruction specifies the operation and the mode. The second word specifies the address
part. Assume that the address field has the value 300. Assume that the content of memory
address 300 is 400. Further, assume that the content of memory address 400 is 600. The
program counter has the value 200 for fetching this instruction. The content of processor
register Ris 800, and the content of an index register XR is 101.
i. According to the given information, detemine the operand values when the direct
and indirect addressing modes are used.
ii.
Evaluate the effective address for each of the following addressing modes.
