ABSTRACT:
The present invention is a desktop personal computer (PC) system having peripheral device bus mastering. The system has a Direct Memory Access (DMA) controller for transferring data to and from the memory of the desktop PC system. A hardware state machine is used for programming the DMA controller, generating and sending command signals, and receiving completion status after the transfer of data is complete. A bus controller is used for implementing a memory data transfer request from the DMA controller means and said hardware state machine means. A device controller, either a Universal Serial Bus (USB) controller or an Infrared Data Association (IrDA) controller, is used for receiving and responding to the command signals from the hardware state machine means, transferring data to and from the DMA controller means, and generating and returning a completion status to the hardware state machine means after the transfer of data is complete.
