Abstract

A computer processor includes control logic for executing LoadUnpack and PackStore instructions. In one embodiment, the processor includes a vector register and a mask register. In response to a PackStore instruction with an argument specifying a memory location, a circuit in the processor copies unmasked vector elements from the vector register to consecutive memory locations, starting at the specified memory location, without copying masked vector elements. In response to a LoadUnpack instruction, the circuit copies data items from consecutive memory locations, starting at an identified memory location, into unmasked vector elements of the vector register, without copying data to masked vector elements. Other embodiments are described and claimed.
