ABSTRACT:
A programmable, byte wise, multimedia bitstream parser comprises an input data organizer, a data management buffer, a register file, a logical unit and a microprogram controller. A data source alternatively provides a bitstream to a parallel or serial port and the input data organizer, which includes a serial to parallel converter and a multiplexer, arranges the incoming data into a parallel stream of bytes for passage to the data management buffer. Status flags are associated with each byte passing through the management buffer to facilitate data processing, including start code and context identification and error handling. The register file includes counters and intermediate data buffers for processing a plurality of layers with data quantities which are not predetermined by syntax. Additionally, the register file is provided in tandem for dual context processing. The microprogram controller is arranged to communicate with the input data organizer, the data management buffer and the register file for the processing of byte wise data. The microprogram controller includes a program on microcode ROM for increased efficiency, accommodation of modifications and debugging, and decreased cost.
