    摘要: A computer system performs direct memory access (DMA) transfers according to a DMA transfer protocol. The computer system may comprise a Peripheral Component Interconnect (PCI) bus that includes an electrical interface as specified by a PCI Local Bus standard. A DMA agent, system memory, and a DMA controller are coupled to the bus. The DMA controller uses the electrical interface of the PCI bus to control a DMA transfer between system memory and the DMA agent. According to one embodiment, a system I/O controller is coupled between the DMA controller and the PCI bus. The system I/O controller passes DMA control information from the DMA controller to the DMA agent using the electrical interface of the PCI bus. The electrical interface of the PCI bus includes a plurality of address lines and a grant signal line coupled to the DMA agent, wherein the system that I/O controller transmits DMA control information to the DMA agent while asserting the grant signal line.

    摘要: A system includes a docking base unit having a first processor and a portable computing device that is dockable to the docking base unit that includes a second processor. A module identifies the number of processors in the system once the portable computing device is docked to the docking base unit and configures the system as a multiprocessor system if more than one processor is identified.

    摘要: An arrangement and method for arbitration to enable split transaction bus protocols provides for a slave to assert a mask signal that sets a mask bit in a mask register when the slave is not ready to complete a requested transaction. A requesting master is forced off the bus and prevented from re-arbitrating while the mask bit is set in the register. When the slave is ready to complete the transaction, a release master signal is asserted which causes the bit in the shift register to be reset. The requesting master is then able to re-arbitrate for use of the bus to complete the transaction. The usable bandwidth of the bus is increased since other masters are able to arbitrate and use the bus until the slave is ready to complete the transaction with the first requesting master.

    摘要: A method and apparatus for converting a signal from a first voltage level to a second voltage level before providing the signal to a processor. A circuit board includes an interface for coupling the circuit board to a peripheral subsystem via a socket. The circuit board also includes a processor that receives signals of a first voltage level, a first signal line, and a second signal line. The first signal line is coupled to the interface and provides a reference signal to the peripheral subsystem that indicates the first voltage level. The second signal line is also coupled to the interface and provides a subsystem signal back from the peripheral subsystem after the signal has been converted to the first voltage level.
