Chapter 6 Applied Instructions 6.9.2 Explanation of Logic Instructions Symbol S 1 ： Data source 1 S 2 ： Data source 2 D ： Operation result 6_ Explanation 1. This instruction applies the logical operator AND to the binary representations in S 1 and S 2 It performs the logical AND operation on each pair of corresponding bits and stores the result in D . 2. Only the DAND instruction can use the 32-bit counter. 3. The result in each position is 1 if the first bit is 1 and the second bit is 1; otherwise, the result is 0.
