Abstract
An apparatus and method for performing right-shifting operations on packed quadword data. For example, one embodiment of a processor comprises: a decoder to decode a right-shift instruction to generate a decoded right-shift instruction; a first source register to store a plurality of packed quadwords data elements; execution circuitry to execute the decoded right-shift instruction, the execution circuitry comprising shift circuitry to right-shift at least first and second packed quadword data elements from first and second packed quadword data element locations, respectively, in the first source register by an amount specified in an immediate value or in a control value in a second source register, to generate first and second right-shifted quadwords; the execution circuitry to cause selection of 16 most significant bits of the first and second right-shifted quadwords to be written to 16 least significant bit regions of first and second quadword data element locations, respectively, of a destination register; and the destination register to store the specified set of the 16 most significant bits of the first and second right-shifted quadwords.
