Frequent ContributorIndeed you can read and write from/to two different buffer simultaneously. You should create two queues, one for each operation, and set the third parameter in clEnqueueRead/WriteBuffer to CL_FALSE so that the operations are performed in a non-blocking fashion. You can then use OpenCL events to synchronize the operations. Also this topic should probably be in the “FPGA Design Tools” section.
