PROBLEM TO BE SOLVED: To provide a SIMD processor which utilizes its hardware resources to achieve higher data processing throughput. SOLUTION: The effective width of the SIMD processor is extended by clocking the instruction processing side of the SIMD processor at a fraction of the rate of the data processing side and by providing multiple execution pipelines, each with multiple data paths. As a result, higher data processing throughput is achieved while an instruction is fetched and issued once per clock. This configuration also allows a large group of threads to be clustered and executed together through the SIMD processor so that greater memory efficiency can be achieved for a certain type of operation like texture memory access performed in connection with graphics processing.
