Abstract
An apparatus and method for enabling a Peripheral Component Interconnect ('PCI') bus to support direct memory access ('DMA') transfers. The apparatus comprises a plurality of DMA controllers, a state machine and an internal storage element. The plurality of DMA controllers transfers DMA requests for an electronic device to the state machine and DMA acknowledges from the state machine to the electronic device. The state machine controls the DMA transfer by performing two transactions for each DMA transfer; namely, a memory cycle and an input/output cycle. The internal storage element acts as a buffer for this multiple cycle DMA transfer.
