Abstract
A computing system includes an issue queue and a microprocessor. The issue queue receives a fused instruction, which includes a first instruction portion fused with a second instruction portion different from the first instruction portion. The microprocessor assigns a first instruction tag (ITAG) to the first instruction portion and a second ITAG to the second instruction portion. The microprocessor determines a first bit that represents the first ITAG, inverts the first bit to determine a second bit that represents the second ITAT, and determines an availability of one or more sources of a second instruction different from the fused instruction based at least in part on the first bit or the second bit.
