What is the effect of each of the following instructions? Assume that MM0 contains 0012ABFF34807F6A16 and MM1 contains F20361111888890A16 at the start of each operation.
a. PAND MM0,MM1
b. PACKuswb MM0,MM1
c. PCMGTb MM0,MM1
d. PCMGTw MM0,MM1
e. PSRAw MM0,5
f. PSRAb MM0,5
The instruction is packed with unsigned saturation. In this example, the two words are packed to create
bytes. The 4?bytes values are converted to 2?byte values by saturating arithmetic rather than simple
truncation
