Decoder Control Register 3 (Stream Buffer Information)

Name:

VDEC_CTLR3

Address:

0x00900018

Access:

Read-write

• STREAM_LEN: Stream Length

Amount of stream data bytes in input buffer. If the given buffer size is not enough for finishing the picture, the correspond-
ing interrupt is given and new stream buffer base address and stream buffer size information should be given.

For VC-1 the buffer must include data for one picture/slice of the picture.

For H264/MPEG4/H263/MPEG2/MPEG1 the buffer must include at least data for one slice/VP of the picture.

For JPEG the buffer size must be a multiple of 256 bytes or the amount of data for one picture.

• INIT_QP: Quantization initialization

Initial value for quantization parameter (picture quantizer).

• ST_COD_EN: Stream start code

Stream start codes exist:

0: Stream doesn't contain start codes.

1: Stream contains start codes.
