Dma request synchronization
WebThe request lines actually correspond to physical lines going from the DMA-eligible devices to the controller itself. Whenever the device will want to start a transfer, it will assert a DMA request (DRQ) by asserting that request line. A very simple DMA controller would only take into account a single parameter: the transfer size. WebSep 8, 2024 · DOORS module archives can be opened with IBM Rational DOORS.

Enable interrupts. Prepare buffer for storing captured counter values Start IC in DMA mode before main loop For high speed operation you may copy data from timerCaptureBuffer to timerCaptureBufferSafe inside these callbacks.
WebThe DMA controller will get data from memory, and then write it to the device. Sometimes we configure the hardware timer to request DMA transfers on a periodic basis. DMA can be used to implement a high-speed data acquisition system. DMA synchronization will be used in situations where high bandwidth and low latency are important.
