6355B–ATARM–21-Jun-10
Decoder Data Flow, Hardware Performs Entropy Decoding (VLC Mode)
Table 46-6.
Notes:
The decoder software starts decoding the first picture by parsing the stream headers (1). Soft-
ware then setups the hardware control registers (picture size, stream start address etc.) and
enables the hardware (2).
In JPEG case, software parses VLC and QP tables from the stream and writes them to a contig-
uous memory area. In VC-1 case, software parses bitplane macroblock control from the stream
and writes it to memory.
Hardware decodes the picture by reading stream, VLC and QP tables for JPEG (3), and the ref-
erence pictures (4) (required for inter picture decoding) from the external memory. Hardware
writes the decoded output picture to memory (5) one macroblock at a time. When the picture has
been fully decoded, or the hardware has run out of stream data, it gives an interrupt with a
proper status flag and provides stream end address for software to continue and returns to initial
state.
In case the hardware detects erroneous stream during decoding, it will return an error interrupt,
and software will start concealing errors for the current picture. Depending on the selected con-
cealment method, software may re-initialize the hardware in the SW entropy decode mode. The
pictures following the corrupted one are decoded in the normal mode until the next error is
detected.
If post-processing is enabled, one or two additional image transfer operations will take place. If
the decoded images are in display order (i.e. no picture re-ordering has been made when
encoding the sequence), and rotation is not used, PP will process the pictures in pipeline with
the decoder. Otherwise, it will first have to read the decoded image that is to be displayed next
from the memory (6), and then write back the processed image (7).
