Host-to-Kernel Stream, Alveo U280

As I understood, there is no qdma shell for the accelerator card U280.

Is there no possibility to stream data from host to the kernels?

In my application, the host should send data blocks over time to the kernel, and the kernel should process and compute this data blocks depending on previous data blocks. Therefore some sort of local storage between the enqueued kernels is needed or a host-to-kernel streaming interface.

Hi @XilinxVivadoUbu ,

Your understanding is correct - there is no QDMA shell for the U280. With this, streaming data transfers (as discussed in the Vitis documentation here: https://www.xilinx.com/html_docs/xilinx2020_2/vitis_doc/streamingconnections.html) are not supported and it is required to use a memory mapped interface to transfer data between the host and the kernels.

Regards,
~John
