A media processing system is provided including a DRAM that includes a plurality of storage locations for storing digital data being processed by said media processing system, said digital data including video data that is compressed in a standardized format, a system for processing said digital data that includes said standardized format compressed video data to produce compressed video images and image data, a system for decoding said standardized format compressed video images to generate full motion video pixel data, a system for sharing said DRAM between said processing means and said decoding means, and a system for producing a full motion video signal from said full motion video pixel data. The media processing system may also have a system for multiplying or combining a first pixel by a second pixel in a single clock cycle. The media processing system may have a plurality of processing elements connected together in parallel, a system for controlling said processing elements with instruction words that have a predetermined number of instructions, and a system for distributing data simultaneously to each of said processing elements.

Systems and methods for efficient processing of multimedia data

Authentication mechanism for interactive home entertainment systems using plug-in cards which do contain software as well as cards which do not contain software. A security bit stream is generated by circuitry on the card and checked by the base system while the system is operating, but only a single signal line of the interface is used for the bit stream. The card also includes a ROM which contains data to be downloaded to the base system. The ROM data is downloaded to the base system via the same signal line of the interface as the serial bit stream. The signal line is used for ROM data download while the base system asserts a 'reset' signal, and is used to carry the serial bit stream for authentication purposes whenever the reset signal is negated.

A system and method for compressing and decompressing variable length instructions contained in variable length instruction packets in a processor having a plurality of processing units is provided that has a compression system with a system for generating an instruction packet containing a plurality of instructions, a system for assigning a compressed instruction having a predetermined length to an instruction within the instruction packet, a shorter compressed instruction corresponding to a more frequently used instruction, and a system for generating an instruction packet containing compressed instructions for corresponding ones of said processing units. The decompression system has a system for storing a plurality of said instruction packets in a plurality of storage locations, a system for generating an address that points to a selected variable length instruction packet in the storage system, and a decompression system that decompresses said compressed instructions in said selected instruction packet to generate a variable length instruction for each of said processing units. The decompression system may also have a system for routing said variable length instructions from the decompression system to each of said processing units.
