What is Understanding Direct Memory Access (DMA) about?
Direct Memory Access (DMA) allows data transfer between I/O devices and main memory without continuous CPU intervention, using a DMA controller that manages memory addresses and control signals. The processor initiates DMA transfers by providing the starting address, word count, and transfer direction, while the DMA controller can operate in cycle stealing or block transfer modes. Bus arbitration methods, including centralized and distributed arbitration, determine which device can access the bus, ensuring
