Question

5. Suppose that the memory of a single accumulator computer contains the values shown below (all values given in hexadecimal), Assume that memory is byte-addressable and that the size of a word is 4 bytes. Assume that the instruction being executed is LOAD WORD some mode 100 ddress Contents 100 400 500 600 700 800 400 600 900 700 800 200 what value is loaded into the accumulator if the addressing mode of the instruction is a. Immediate b. Direct c. Indirect d. Indexed with the index register containing 100

Explanation / Answer

1.If the addressing mode of induction is Immediate address=400,contents=600 values are loaded in to the accumulator.

2.If the addressing mode of induction is Direct address=700,contents=800 values are loaded in to the accumulator.

3.If the addressing mode of induction is Indirect address=100,contents=400 values are loaded in to the accumulator.

4.If the addressing mode of induction is Indexed with the index register containing 100 address=800,contents=100 values are loaded in to the accumulator.
