The PSRLD instruction shifts the two 32-bit operands in the destination operand (an
MMX register) to the right by the number of bit positions indicated by
mmreg2/mem64 or by imm8, the 8-bit immediate operand. The shifted values are zero
filled from the left. The two 32-bit results are stored in the MMX register specified as
the destination operand.

The emulate MMX instruction bit (EM) of the control register (CR0) is set to 1.
Save the floating-point or MMX state if the task switch bit (TS) of the control
register (CR0) is set to 1.
During instruction execution, the stack segment limit was exceeded.
During instruction execution, the effective address of one of the segment
registers used for the operand points to an illegal memory location.
One of the instruction data operands falls outside the address range 00000h
to 0FFFFh.
A page fault resulted from the execution of the instruction.
An exception is pending due to the floating-point execution unit.
