Abstract:
A single semiconductor chip for performing audio, video, and 3-D graphics functions comprising:a digital bitstream processor for decoding variable length code digital bitstream data;a digital signal processor coupled to the digital bitstream processor which performs video and audio decompressing, filtering, geometry processing, and performing wavetable synthesis for audio;a display processor coupled to the digital signal processor which supports both geometric 3-D graphics and image data types, wherein an update interval sychronized to a video frame is defined, the update interval is divided into a plurality of partitions such that audio data is processed during a first partition, video data is processed during a second partition, and graphics data is processed during a third partition, the processing being performed in a sequential, time-division multiplex scheme whereby the single semiconductor chip processes all three partitions in a single video frame;a memory controller coupled to an external memory array, said memory array used to store image data and instruction data;an audio/video input/output port coupled to the display processor.
