  • Publication number: 20200089494
    Abstract: A processor includes a decode unit to decode an instruction that is to indicate a first source packed data operand that is to include at least four data elements, to indicate a second source packed data operand that is to include at least four data elements, and to indicate one or more destination storage locations. The execution unit, in response to the instruction, is to store at least one result mask operand in the destination storage location(s). The at least one result mask operand is to include a different mask element for each corresponding data element in one of the first and second source packed data operands in a same relative position.

  • Patent number: 10545761
    Abstract: Instructions and logic provide SIMD permute controls with leading zero count functionality. Some embodiments include processors with a register with a plurality of data fields, each of the data fields to store a second plurality of bits. A destination register has corresponding data fields, each of these data fields to store a count of the number of most significant contiguous bits set to zero for corresponding data fields. Responsive to decoding a vector leading zero count instruction, execution units count the number of most significant contiguous bits set to zero for each of data fields in the register, and store the counts in corresponding data fields of the first destination register. Vector leading zero count instructions can be used to generate permute controls and completion masks to be used along with the set of permute controls, to resolve dependencies in gather-modify-scatter SIMD operations.

  • Patent number: 10503502
    Abstract: A processor includes a decode unit to decode an instruction indicating a source packed data operand having source data elements and indicating a destination storage location. Each of the source data elements has a source data element value and a source data element position. An execution unit, in response to the instruction, stores a result packed data operand having result data elements each having a result data element value and a result data element position. Each result data element value is one of: (1) equal to a source data element position of a source data element, closest to one end of the source operand, having a source data element value equal to the result data element position of the result data element; and (2) a replacement value, when no source data element has a source data element value equal to the result data element position of the result data element.
