Name: VDEC_CTLR2
Address: 0x00900014
Access: Read-write
DCCB: DC Component of the Cb
Defines which VLC table should be used for decoding DC components of the Cb.
0: First
1: Second
Note: For luminance the first table is always used
DCCR: DC Component of the Cr
Defines which VLC table should be used for decoding DC components of the Cr.
0: First
1: Second
Note: For luminance the first table is always used.
ACCB: AC Component of the Cb
Defines which VLC table should be used for decoding AC components of the Cb.
0: First
1: Second
Note: For luminance the first table is always used.
ACCR: AC Component of the Cr
Defines which VLC table should be used for decoding AC components of the Cr.
0: First
1: Second
Note: For luminance the first table is always used.
END: End of JPEG Image in the Stream
0: Current stream buffer does not contain the end of a JPEG image. HW will not flush the stream data pipeline after a buffer
empty request.
1: Current stream buffer contains the end of a JPEG image. HW will flush data pipeline and will not request more stream
providing it finds the EOI pattern at the end.
