Abstract
The present invention is directed to a system and method for selecting instruction words from a memory system for simultaneous execution in an execution unit of a computer system. In one example, an instructor selector unit of the present invention employs an addressing unit to fetch instructions from an instruction cache. The instructor selector unit also employs a receiver unit for buffering and transferring multiple aligned as well as misaligned instructions. The instruction selector unit supplies these instructions to an instruction execution unit (having an integer unit and a floating point unit), which is capable of executing two bundled instructions simultaneously. The instruction selector unit can provide instructions to the instruction execution unit individually, or as a bundled pair.
