Abstract
Within a superscalar processor, multiple groups of instructions are dispatched simultaneously to a plurality of execution units. A renaming mechanism is utilized to permit out-of-order execution of these instructions within the multiple groups. The renaming mechanism includes a rename table allocated for each dispatched group. A delay register is implemented between a portion of the dispatch queue dispatching a second one of the groups of instructions and a second one of the rename tables.
