Functional Illustration of the PSRAW Instruction
The following list explains the functional illustration of the PSRAW instruction:
I
The value 0000_0000_0000_0008h in mmreg2/mem64 indicates a shift of 8 bit
positions to the right.
The 16-bit negative value 8800h in mmreg1 is shifted 8 bit positions to the right
with sign fill from the left and stored in mmreg1 as FF88h.
The 16-bit negative value EC00h in mmreg1 is shifted 8 bit positions to the right
with sign fill from the left and stored in mmreg1 as FFECh.
The 16-bit positive value 0F00h in mmreg1 is shifted 8 bit positions to the right
with sign fill from the left and stored in mmreg1 as 000Fh.
The 16-bit positive value 7F00h in mmreg1 is shifted 8 bit positions to the right
with sign fill from the left and stored in mmreg1 as 007Fh.
