Manufacturer:FSC Description:The DMA controller is a state-driven address and control signal generator, which permits data to be transferred directly from an I/O device to memory or vice versa without ever being stored in a temporary register. This can greatly increase the data transfer rate for sequential operations, compared with processor move or repeated string instructions.Memory-to-memoryoperationsrequire temporary internal storage of the data byte between generation of the source and destination addresses, so memory-to-memory transfers take place at less than half the rate of I/O operations, but still much faster than with central processor techniques. The maximum data transfer rates obtainable with the 82C37A are shown in Figure 1. |
