Fill in the blank areas in the following table. The memory accesses column should include all memory accesses to get the instruction, the operands and to store the result. Assume each memory access can transfer at most one word.
| Intruction | # of words in entire instruction | # of memory accesses |
|---|---|---|
| add.w d0,1550 | ||
| add.w #1550,d0 | ||
| addq.w #3,d2 | ||
| move.b (a2),(a3)+ |
| Intruction | # of words in entire instruction | # of memory accesses |
|---|---|---|
| add.w d0,1550 | 3 (or 2)* | 5 (or 4)* |
| add.w #1550,d0 | 2 | 2 |
| addq.w #3,d2 | 1 | 1 |
| move.b (a2),(a3)+ | 1 | 4 |
