摘要： An apparatus is described having instruction execution logic circuitry to execute first, second, third and fourth instruction. Both the first instruction and the second instruction insert a first group of input vector elements to one of multiple first non overlapping sections of respective first and second resultant vectors. The first group has a first bit width. Each of the multiple first non overlapping sections have a same bit width as the first group. Both the third instruction and the fourth instruction insert a second group of input vector elements to one of multiple second non overlapping sections of respective third and fourth resultant vectors. The second group has a second bit width that is larger than said first bit width. Each of the multiple second non overlapping sections have a same bit width as the second group. The apparatus also includes masking layer circuitry to mask the first and third instructions at a first resultant vector granularity, and, mask the second and fourth instructions at a second resultant vector granularity.

摘要： In one embodiment a processing device implements a set of instructions to perform an inverse centrifuge operation using vector or general purpose registers. The inverse centrifuge operation interleaves bits from opposite regions of a source and writes the interleaved bits to a destination. The instructions use a control mask where each bit with a mask value of one is obtained from one side of the source register or vector elements with a mask of zero are obtained from the opposing side.

摘要： 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.
