摘要: An apparatus and method for mask compression. For example, one embodiment of a processor comprises: a source mask register to store a plurality of mask bits including a plurality of set bits and a plurality of bits that are not set; a destination mask register to store set bits read from the source mask register; and mask compression logic to read each of the set bits from the source mask register and to store the set bits in contiguous bit locations on one side of the destination mask register.
