The VCU core is a dedicated circuitry located in the PL to enable maximum flexibility for a wide selection of use cases, memory bandwidth being a key driver. Whether the application requires simultaneous 4K UHD at 60 Hz encoding and decoding or a single SD stream to be processed, a system design and memory topology can be implemented that balances performance, optimization, and integration for the specific use case. The following figure shows the use case example where the VCU core works with the PS and the PL DDR external memory.
