Graphic system for masking multiple non-contiguous bytes having decode logic to selectively activate each of the control lines based on the mask register bits |
摘要 |
A partial store instruction and associated logic for storing selected bytes of a group of bytes in a register to a designated memory location. A mask in a separate register is used to enable particular bytes to be written, with only enabled bytes being written to the final location. The mask can be previously generated as a result of a comparison or other operation. The creation of the mask and the execution of a partial store instruction can also be used as a prefetch instruction, eliminating the need for a separate opcode for a prefetch.
