SYSTEMS, APPARATUSES, AND METHODS FOR PERFORMING CONVERSION OF A LIST OF INDEX VALUES INTO A MASK VALUE

摘要

Embodiments of systems, apparatuses, and methods for performing in a computer processor conversion of a list of index values into a mask value in response to a single vector packed conversion of a list of index values into a mask value instruction that includes a destination writemask register operand, a source vector register operand, and an opcode are described.

1. A method of performing in a computer processor conversion of a list of index values into a mask value in response to a single vector packed conversion of a list of index values into a mask value instruction that includes a destination writemask register operand, a source vector register operand, and an opcode, the method comprising steps of:
executing the single vector packed conversion of a list of index values into a mask value instruction to determine a value stored in each packed data element position of the source vector register; and storing a 1 into bit positions of the destination writemask register that correspond to the determined values.
