Abstract: 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.

Abstract: Digital image data is encoded using a variable-length code which is described by a group of parameter values. Each parameter value describes a set of code values; each code value corresponds to a possible value of the data which is to be encoded. When the data is encoded, the parameter values are appended to the encoded data. A decoder stores the parameter values into a memory and then combines data values derived from the encoded data with parameter values from the memory to generate decoded data values. Each code word includes a prefix which indicates a number of successive parameter values which are to be summed, and a population index which is to be added to the summed parameter values to produce a decoded data value.
