ABSTRACT:
A decoder for compressed video signals comprises a central processing unit (CPU), a dynamic random access memory (DRAM) controller, a variable length code (VLC) decoder, a pixel filter and a video output unit. The microcoded CPU performs dequantization and inverse cosine transform using a pipelined data path, which includes both general purpose and special purpose hardware. In one embodiment, the VLC decoder is implemented as a table-driven state machine where the table contains both control information and decoded values.
