Running the codec
This section describes how the BIT processor controls the video codec and communicates with a host
processor.
The provided firmware can handle 8 processes simultaneously. Each process can have difference format –
MPEG-4, H.263P3, H.264 or VC-1 - and codec process-encoding or decoding. For example, it is possible to
handle 1 MPEG-4 encoding process, 1 H.264 encoding process, 1 H.263P3 decoding process and 1 VC-1
decoding process simultaneously. You can encode image and/or decode bitstream as following.
Create processes: You can create and configure processes.
-
Running processes: At a proper time instance, you can run a specific process. The proper time instance
-
means when the codec is in idle state and image to be encoded or bitstream to be decoded is readyin the
external memory.
Quit processes: You can quit a specific process.
-
Figure 21.5 illustrates simplified state diagram for running the codec.
