Abstract:
A set-top box for processing streams of media data which comprise a combination of at least two of audio, video, radio, graphics, encryption, authentication, and networking information. The set-top box processes streams of media data and has at least one programmable media processor (12) for receiving, processing and transmitting the stream of media data over the bi-directional communications network. The processor executes group instructions to read a plurality of data elements of the media data stream from a register file (110), to perform, on the data elements, group operations including both group integer and group floating point operations capable of dynamically partitioning the data by each specifying one of a plurality of data element sizes, and to write concatenated results in the register file.

Abstract:
A general purpose, programmable media processor (12) for processing and transmitting a media data streams. The media processor (12) incorporates an execution unit (100) that maintains substantially peak data through out of media data streams. The execution unit (100) includes a dynamically partionable multi-precision arithmetic unit (102), programmable switch (104) and programmable extended mathematical element (106). A high bandwidth external interface (124) supplies media data streams at substantially peak rates to a general purpose register file (110) and the execution unit. A memory management unit, and instruction and data cache/buffers (118, 120) are provided. The general purpose, programmable media processor (12) is disposed in a network fabric consisting of fiber optic cable, coaxial cable and twisted pair wires to transmit, process and receive single or unified media data streams.
Abstract:
A programmable processor and method for improving the performance of processors by expanding at least two source operands, or a source and a result operand, to a width greater than the width of either the general purpose register or the data path width. The present invention provides operands which are substantially larger than the data path width of the processor by using the contents of a general purpose register to specify a memory address at which a plurality of data path widths of data can be read or written, as well as the size and shape of the operand. In addition, several instructions and apparatus for implementing these instructions are described which obtain performance advantages if the operands are not limited to the width accessible number of general purpose registers.

A system for processing streams of media data in a wireless bi-directional communications network. The system is capable of transmitting and receiving at least one stream of media data comprising a combination of at least two of audio, video, radio, graphics, encryption, authentication, and networking information to and from system devices. The system devices each have at least one programmable media processor (12) for receiving, processing and transmitting the stream of media data over the bi-directional communications network. The processor executes group instructions to read a plurality of data elements of the media data stream from a register file (110), to perform, on the data elements, group operations including both group integer and group floating point operations capable of dynamically partitioning the data by each specifying one of a plurality of data element sizes, and to write concatenated results in the register file.
