    摘要: An apparatus and method are described for down-converting from a source operand to a destination operand with masking. For example, a method according to one embodiment includes the following operations: reading a source operand value to be down-converted from a first value to a down-converted value and stored in a destination location; reading each mask register bit stored in a mask register, the mask register bit(s) indicating whether to perform a masking operation or a conversion operation on the source operand value; if the mask register bit(s) indicates that a masking operation is to be performed, then performing a specified masking operation and storing the results of the masking operation in the destination location; and if the mask register bit(s) indicates that a masking operation is not to be performed, then down-converting the source operand value and storing the down-converted value in the specified destination location.

    摘要: Methods, apparatus, instructions and logic provide SIMD vector sub-byte decompression functionality. Embodiments include shuffling a first and second byte into the least significant portion of a first vector element, and a third and fourth byte into the most significant portion. Processing continues shuffling a fifth and sixth byte into the least significant portion of a second vector element, and a seventh and eighth byte into the most significant portion. Then by shifting the first vector element by a first shift count and the second vector element by a second shift count, sub-byte elements are aligned to the least significant bits of their respective bytes. Processors then shuffle a byte from each of the shifted vector elements' least significant portions into byte positions of a destination vector element, and from each of the shifted vector elements' most significant portions into byte positions of another destination vector element.

    摘要: Instructions and logic provide vector compress and rotate functionality. Some embodiments, responsive to an instruction specifying: a vector source, a mask, a vector destination and destination offset, read the mask, and copy corresponding unmasked vector elements from the vector source to adjacent sequential locations in the vector destination, starting at the vector destination offset location. In some embodiments, the unmasked vector elements from the vector source are copied to adjacent sequential element locations modulo the total number of element locations in the vector destination. In some alternative embodiments, copying stops whenever the vector destination is full, and upon copying an unmasked vector element from the vector source to an adjacent sequential element location in the vector destination, the value of a corresponding field in the mask is changed to a masked value. Alternative embodiments zero elements of the vector destination, in which no element from the vector source is copied.
