    摘要: A processor core that includes a hardware decode unit to decode a vector frequency compress instruction that includes a source operand and a destination operand. The source operand specifying a source vector register that includes a plurality of source data elements including one or more runs of identical data elements that are each to be compressed in a destination vector register as a value and run length pair. The destination operand identifies the destination vector register. The processor core also includes an execution engine unit to execute the decoded vector frequency compress instruction which causes, for each source data element, a value to be copied into the destination vector register to indicate that source data element's value. One or more runs of the source data elements equal are encoded in the destination vector register as the predetermined compression value followed by a run length for that run.

    摘要: A method of an aspect includes receiving a masked packed rotate instruction. The instruction indicates a first source packed data including a plurality of packed data elements, a packed data operation mask having a plurality of mask elements, at least one rotation amount, and a destination storage location. A result packed data is stored in the destination storage location in response to the instruction. The result packed data includes result data elements that each correspond to a different one of the mask elements in a corresponding relative position. Result data elements that are not masked out by the corresponding mask element include one of the data elements of the first source packed data in a corresponding position that has been rotated. Result data elements that are masked out by the corresponding mask element include a masked out value. Other methods, apparatus, systems, and instructions are disclosed.

    摘要: A processor core including a hardware decode unit to decode vector instructions for decompressing a run length encoded (RLE) set of source data elements and an execution unit to execute the decoded instructions. The execution unit generates a first mask by comparing set of source data elements with a set of zeros and then counts the trailing zeros in the mask. A second mask is made based on the count of trailing zeros. The execution unit then copies the set of source data elements to a buffer using the second mask and then reads the number of RLE zeros from the set of source data elements. The buffer is shifted and copied to a result and the set of source data elements is shifted to the right. If more valid data elements are in the set of source data elements this is repeated until all valid data is processed.
