    摘要: A portable computer system includes an input device such as a keyboard, a display, and a processor which is operable in a normal operational mode and in a reduced power mode, the processor carrying out program execution in each of the normal operational mode and reduced power mode. A timing arrangement switches the processor from its normal operational mode to its reduced power mode in response to the absence of any of a plurality of predetermined events during a predetermined time interval, the predetermined events including actuation of keys on the keyboard and transmission of information to the video display.

    摘要: A portable computer system includes a housing, a lid supported on the housing for movement between open and closed positions, a keyboard supported on the housing below the lid, and a display provided on the lid. When the lid is opened, the keyboard is accessible and the display is visible, whereas when the lid is closed the keyboard and display are hidden and protected. The computer system includes a processor disposed within the housing and having a first operational mode in which it executes instructions and a second operational mode in which it is in a reduced power suspend state from which it can automatically exit in response to a predetermined condition. The system includes an arrangement responsive to closing of the lid when the processor is in its first operational state for switching the processor to its second operational state.

    摘要: An information handling system includes a processing system, a low-power processing system, and a chipset. The processing system is configured to operate using a power system configured to power a shared resource of the processing system and a non-shared resource of the processing system, and to disable the non-shared resource during a reduced operating state of the processing system. The low-power processing system is configured to access the shared resource of the processing system during operation of the low-power processing system, wherein the operation of the low-power processing system is separate from the operation of the processing system. The chipset includes a processor of the processing system and operable to be enabled during operation of the processing system, wherein the processor is configured to be disabled during operation of the low-power processing system.

    摘要: An interrupt polling unit included within a bus interface unit of a microprocessor is provided. The interrupt polling unit causes a periodic interrupt acknowledge bus transaction to occur. If an interrupt controller receiving the interrupt acknowledge bus transaction returns an interrupt vector indicative of an interrupt service routine, then the microprocessor executes the interrupt service routine. The number of interrupt acknowledge bus transactions associated with the interrupt is reduced from two to one, and the microprocessor effectively prefetches the interrupt service routine before the interrupt is actually signaled. In one embodiment, the interrupt polling unit causes an interrupt acknowledge bus transaction to occur at the expiration of a programmable time interval. Another embodiment of the interrupt polling unit causes an interrupt acknowledge bus transaction subsequent to the occurrence of a bus transaction programmed by the user.
