That is the strange naming of the ip block inside the soc.
I.e. the rk3588 TRM lists a number of different video encoders and decoders:
- VDPU121 is decoding h.263 and mpeg1,2,4
- VDPU381 is decoding h.265, h.264 and some more
- VDPU720 is decoding jpeg
- VDPU981 decodes AV1
- VEPU121 is the jpeg encoder above
- VEPU580 encodes h.264 and h.265
Each of those are separate IP blocks with their own io-memory, their own
interrupts and their own iommus, etc.
