The following sections detail the performance characteristics of the H.264/H.265 Video Decode Unit.

Maximum Frequencies

The typical clock frequencies for the target devices are described in Versal AI Core Series Data Sheet: DC and AC Switching Characteristics (DS957) and Versal AI Edge Series Data Sheet: DC and AC Switching Characteristics (DS958). The maximum achievable clock frequency of the system can vary. The maximum achievable clock frequency and all resource counts can be affected by other tool options, additional logic in the device, using a different version of Xilinx® tools and other factors.

Throughput

The VDU supports decoding up to four simultaneous instances of 4K UHD resolution at 60 Hz. This throughput can be four streams at 4K UHD or can be divided into smaller streams. Several combinations can be supported with different resolutions, provided the cumulative throughput does not exceed four times 4K UHD at 60 Hz.
