Abstract
Disclosed is a method that simultaneously transfers DMA data from a peripheral device to a hardware assist function and processor memory. A first DMA transfer is configured to transfer data from the peripheral to a peripheral DMA engine. While receiving the data, the DMA engine simultaneously transfers this data to processor memory. The DMA engine also transfers a copy of the data to a hardware assist function. The DMA engine may also simultaneously transfer data from processor memory to a peripheral device while transferring a copy to a hardware assist function.
