Iio_dma_buffer_submit_block

WebThis block reads data from the direct-memory-access (DMA) buffer of the specified AXI4-Stream IP core device by using the Industrial I/O (IIO) library drivers. The AXI4-Stream IIO Read block enables you to achieve a low-latency, high-throughput data transmission between your model deployed on the processor and the IP core on the FPGA.
