US Patent 7480787 Method and structure for pipelining of SIMD conditional moves

A mask is first generated in a general-purpose integer register. The mask is generated by executing a single instruction multiple data (SIMD) instruction on a plurality of operands stored in a plurality of registers and by writing the result to the general-purpose integer register. Next, a conditional-move mask is generated in a register using the mask, and then the conditional-move mask is used in selecting operands from the plurality of operands to generate a result in another register.
