Abstract
An audio and video decoder for decoding audio, video and sub-picture streams in a disc player. The audio and video decoder has associated therewith a memory for storing commands and status information for each command. The audio and video decoder is responsive to commands received from a host to control audio and video decoding processes. The audio and video decoder includes a host interface and a command processor. The command processor includes a transfer mechanism for transferring commands received at a command buffer in the memory to a command FIFO in the memory and a status monitor for tracking an execution status of each command stored in the command FIFO and for updating a status word which is stored along with each command in the command FIFO. The command processor returns a pointer to the host for a unique address in memory for the status word for each command stored in the command FIFO.
