Abstract: An apparatus and method for performing a vector permute. For example, one embodiment of a processor comprises: a source vector register to store a plurality of source data elements; a destination vector register to store a plurality of destination data elements; a control vector register to store a plurality of control data elements, each control data element corresponding to one of the destination data elements and including an N bit value indicating whether a source data element is to be copied to the corresponding destination data element; vector permute logic to compare the N bit value of each control data element to an N bit portion of an immediate to determine whether to copy a source data element to the corresponding destination data element, wherein if the N bit values match, then the vector permute logic is to identify a source data element using an index value included in the control data element and to responsively copy the source data element to the corresponding destination data element in the destination vector register.

Abstract: 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.

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

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.
