Publication number: 20240143530Abstract: Techniques for improving the handling of peripherals in a computer system, including through the use of a DMA control circuit that helps manage the flow of data between memory and the peripherals via an intermediate storage buffer. The DMA control circuit is configured to control timing of DMA transfers between sample buffers in the memory and the intermediate storage buffer. The DMA control circuit may output a priority value of the DMA control circuit for accesses to memory, where the priority value based on stored quality of service (QoS) information and current channel data buffer levels for different DMA channels. The DMA control circuit may separately arbitrate between multiple active transmit and receive channels. Still further, the DMA control circuit may store, for a given data transfer over a particular DMA channel, timestamp information indicative of completion of the DMA and peripheral-side operations.Type: ApplicationFiled: January 4, 2024Publication date: May 2, 2024Inventors: Brett D. George, Rohit K. Gupta, Do Kyung Kim, Paul W. Glendenning
