摘要: A Direct Memory Access (DMA) Acceleration Device for substantially increasing a data transfer rate between system memory and an Input/Output (I/O) device use in processing system. The DMA enables the to subtantially double I/O by generating necessary control address signals. In receive operation, reads from while host processor simultaneously writes previous memory. Similarly, transmit subsequent Transmit Receive State Machines of are programmed sequencing signals during mode, being absolutely transparent non-DMA mode operation.
