Methods and apparatus for efficient modification of values within computing registers

摘要

In some embodiments, an apparatus includes a register having a first portion and a second portion. The first portion of the register has multiple bits and the second portion of the register has multiple bits. Each bit from the multiple bits of the first portion of the register is associated with a bit from the multiple bits of the second portion of the register such that a bit from the multiple bits of the first portion of the register is set for its associated bit from the multiple bits of the second portion of the register to be written.
