摘要: A fast resume of a computer from a low power mode to a normal operating mode captures a power down message from the operating system of the computer to devices connected thereto. In response to the captured message, the device manager is instructed to remove the device from the operating system. The computer is powered down with the device removed. The system is later powered up with the device removed, allowing for faster resume to normal operation. After the computer has returned to normal operation, the device manager reinstates the removed device. The program to capture the power down message can be above the device driver in the driver stock or be an application running in the user mode of the operating system.

摘要: A PCI Express to PCI bridge enables upstream and downstream isochronous data transfer by modifying the PCI bus arbiter so that the PCI device on the PCI bus is treated as a virtual port for the bridge. Data from the PCI device is assigned via a port arbitration table to sufficient bandwidth so that the data from the PCI device can be transferred upstream isochronously. The bridge also handles downstream isochronous data transfer.
