description: |
|
||
|
|
The video decoding IP lies within the DOS memory region,
|
||
|
|
except for the hardware bitstream parser that makes use of an undocumented
|
||
|
|
region.
|
||
|
|
|
||
|
|
It makes use of the following blocks:
|
||
|
|
- ESPARSER is a bitstream parser that outputs to a VIFIFO. Further VDEC blocks
|
||
|
|
then feed from this VIFIFO.
|
||
|
|
- VDEC_1 can decode MPEG-1, MPEG-2, MPEG-4 part 2, MJPEG, H.263, H.264, VC-1.
|
||
|
|
- VDEC_HEVC can decode HEVC and VP9.
|
||
|
|
|
||
|
|
Both VDEC_1 and VDEC_HEVC share the "vdec" IRQ and as such cannot run
|
||
|
|
concurrently.
