The following sections detail the performance characteristics of the H.264/H.265 Video Codec Unit.
Maximum Frequencies
The typical clock frequencies for the target devices are described in the Zynq UltraScale+ MPSoC Data Sheet: DC and AC Switching Characteristics (DS925). 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 AMD tools and other factors.
Throughput
The VCU supports simultaneous encoding and decoding up to 4K UHD resolution at 60 Hz. This throughput can be a single stream at 4K UHD or can be divided into up to 32 smaller streams of up to 480p at 30 Hz. Several combinations of one to 32 streams can be supported with different resolutions provided the cumulative throughput does not exceed 4K UHD at 60 Hz.
