QUESTION 8:
What is the bitwise AND of the following?
FEED BECA ----
FEED 1111 1110 1110 1101 BECA 1011 1110 1100 1010 ---- ---- ---- ---- ---- FEEF 1111 1110 1110 1111
It is usually easiest to translate into bits, do the OR, then translate back to hex.
| AND Operation on Bits | ||||
|---|---|---|---|---|
| first operand | 0 | 0 | 1 | 1 |
| second operand | 0 | 1 | 0 | 1 |
| __ | __ | __ | __ | |
| result | 0 | 0 | 0 | 1 |
MIPS has an AND instruction:
and d,s,t # $d <-- bitwise AND between $s with $t.
Recall that the result of AND is one only when both operand bits are one.
