An and" operation simply says both A and B are equal to a logical then set the result. ogical operations work at a bit level, that is, for you to decide what the outcome of a logical operation will be you have to understand the data Suppose we "and" and with the instruction ANDI W#1 op' and op contained If we look at the number in binary is 0001 and 1 1001. When these two numbers are anded. the processor looks at the numbers like this: 3210 Bit number 0001 in binary 1001 in binary First will look at both bit 3's. It says I have a l and a0 so I don't have two 1's. Therefore the result is zero Then it looks at bit 2's, which are both zero so the result is ...
