Abstract
An optimized, superscalar microprocessor architecture for supporting graphics operations in addition to the standard microprocessor integer floating point operations is provided. Independent execution paths are provided for different graphics instructions to allow parallel execution of instructions which commonly occur together. The invention also optimizes the use of register file accesses to avoid, as much as possible, interference between graphics instructions needing to access a register file and other instruction accesses which would occur in combination with graphics instructions, thereby avoiding pipeline stalls and allowing parallel execution.
