Single-instruction multiple-data is a new class of integrated video signal processors especially suited for real-time processing of two-dimensional images. The single-instruction, multiple-data architecture is adopted to exploit the high degree of parallelism inherent in many video signal processing algorithms. Features have been added to the architecture which support conditional execution and sequencing-an inherent limitation of traditional single-instruction multiple-data machines. A separate transfer engine offloads transaction processing from the execution core, allowing balancing of input/output and compute resources-a critical factor in optimizing performance for video processing. These features, coupled with a scalable architecture allow a united programming model and application driven performance.
