Read and write masks update instruction for vectorization of recursive computations over interdependent data |
摘要 |
A processor executes a mask update instruction to perform updates to a first mask register and a second mask register. A register file within the processor includes the first mask register and the second mask register. The processor includes execution circuitry to execute the mask update instruction. In response to the mask update instruction, the execution circuitry is to invert a given number of mask bits in the first mask register, and also to invert the given number of mask bits in the second mask register. |

1. An apparatus comprising:
a register file including a first mask register and a second mask register; and execution circuitry coupled to the register file to execute a mask update instruction, wherein in response to a single instance of the mask update instruction, the execution circuitry is to invert a given number of mask bits in the first mask register, and to invert the given number of mask bits in the second mask register. |
