RunIndex
R/W
3'b100 (SET_FRAME_BUF): Set decoded/
reconstructed frame buffer SDRAM address and
maximum frame buffer number. Before
encode/decode picture run command, host must
inform frame buffer SDRAM address to BIT
processor then BIT processor arrange frame buffer
for decoded/reconstructed image and return frame
buffer index to host at end of encoding/decoding
picture.
3'b101 (ENCODE HEADER): Encode header. For
example in H.264 case, SPS (Sequence Parameter
Set), PPS (Picture Parameter Set) may be inserted
between picture boundary by this command.
3'b110 (ENC PARA SET): Encode SPS, PPS to BIT
processor's parameter set buffer. In H.264, host can
obtain SPS / PPS by this command
3'b111 (DEC PARA SET): Add SPS, PPS to BIT
processor's parameter set buffer. In H.264, multiple
SPS / PPS is allowed and host may inform one of
the parameter set to BIT processor for use in
decoding process.
4'b1111 (GET F/W VER): A command to check F/W
version. This command is only applicable to F/W
version later than 1.2.5.
Function
Host writes the codec process index to this register
before every writing run command.
BIT processor can execute max 4 encoding/decoding
processes simultaneously. If more than one process is
running, each process must be assigned different
process index by this register. For example, when 1
MPEG4 Decoder + 1 AVC Decoder + 1 AVC Encoder
are running simultaneously, MPEG4 Decoder is
assigned process index '0', AVC Decoder is assigned
process index '1' and AVC Encoder is assigned
process index '2'.
