Abstract: In an electronic system, a DMA circuit is supplied with a device selection signal that indicates a processor is accessing or going to access a memory. If the DMA circuit finds that the processor is not accessing or not going to access the memory, the DMA circuit starts its DMA operations. Once the DMA circuit finds that the processor is going to access the memory, the DMA circuit stops its DMA operation and return the use of the memory to the processor.
