WSWAP

Word swap bit; swaps two 32-bit words in one 64-bit data word, so that word 0 is transferred before word 
1. Does not change the position of the bits within each word.

SSWAP

Short swap bit; swaps the two 16-bit short words in one 32-bit data word, so that short 0 is transferred 
before short 1. Does not change the order of the bits within each short.

BSWAP

Byte swap bit; swaps bytes 0 and 1, and also bytes 2 and 3, in a 32-bit data word, so that the bytes are 
positioned 1, 0, 3, 2. Does not change the position of the bits within each byte.

Below is the structure of a 64-bit data word, with no swapping in effect.
