Web7 feb. 2024 · From: Alexandru Ardelean A part of the logic in the iio_dma_buffer_exit() is required for the change to add mmap support to IIO buffers. This change splits the logic into a separate function, which will be re-used later.

WebThe AXI4-Stream IIO Write (HOST) block writes data to the direct-memory-access (DMA) buffer of the specified AXI4-Stream IP core device on a connected Xilinx ® SoC device from a running Simulink ® model. This block enables low-latency high-throughput data transmission between your simulation model and the IP core on the SoC device.

WebThe buffer-dma code was using two queues, incoming and outgoing, to manage the state of the blocks in use. While this totally works, it adds some complexity to the code, especially since the code only manages 2 blocks. easier to just check each block's state manually, and keep a counter for the next block to dequeue.
