Abstract
A data transfer method with peripheral precharge wherein a starting portion of an output data block targeted for a peripheral is transferred to an output buffer for the peripheral using programmed I/O or slave cycles and wherein a virtual address of the output data block is translated into a physical address while the peripheral begins transferring the starting portion from the output buffer and over an output path. A direct memory access operation by the peripheral transfers a remainder portion of the output data block into the output buffer.
