Abstract: 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.

Abstract: A method is described that includes reading a first read mask from a first register. The method also includes reading a first vector operand from a second register or memory location. The method also includes applying the read mask against the first vector operand to produce a set of elements for operation. The method also includes performing an operation of the set elements. The method also includes creating an output vector by producing multiple instances of the operation's result. The method also includes reading a first write mask from a third register, the first write mask being different than the first read mask. The method also includes applying the write mask against the output vector to create a resultant vector. The method also includes writing the resultant vector to a destination register.

Abstract: An apparatus is described that includes an execution unit to execute a first instruction and a second instruction. The execution unit includes input register space to store a first data structure to be replicated when executing the first instruction and to store a second data structure to be replicated when executing the second instruction. The first and second data structures are both packed data structures. Data values of the first packed data structure are twice as large as data values of the second packed data structure. The execution unit also includes replication logic circuitry to replicate the first data structure when executing the first instruction to create a first replication data structure, and, to replicate the second data structure when executing the second data instruction to create a second replication data structure. The execution unit also includes masking logic circuitry to mask the first replication data structure at a first granularity and mask the second replication data structure at a second granularity. The second granularity is twice as fine as the first granularity.
