Abstract: A device and method for transferring data, address and status information concerning a former I/O bus cycle before a system management interrupt is initiated. A plurality of system management shadow registers samples information from a system bus. Such information is obtained by a register accessing the plurality of system management shadow registers through a common shadow port.

Abstract: A device and method for power management of direct memory access ("DMA") slaves through DMA traps. The device comprises a plurality of registers coupled with conventional logic in order to generate a control signal for disabling direct memory access transfer requests for a powered-off DMA slave until the slave is re-powered. The method for managing power comprises steps of unmasking bits in a register containing information regarding which DMA slaves have been powered-off. Next, the DMA Controller consults a power management macro ("PMM") to determine whether a DMA transfer request involves a powered-off DMA slave. If not, the DMA transfer continues. However, if the DMA transfer does involve a powered-off DMA slave, then a main software application in operation is temporarily halted and the PMM generates a SMI signal and outputs the SMI signal to the central processing unit ("CPU") while keeping the disable control signal asserted, which effectively disables the DMA channel.

Abstract: The present invention relates to an apparatus and method for controlling a CPU clock in response to certain events with a system in order to conserve power usage. These events can be programmably enabled or disabled. The apparatus comprises a circuit for detecting enabled Stop Clock events requiring the CPU clock to temporarily cease operation. In combination therewith, the present invention includes a circuit for detecting enabled Stop Break events which are used to re-start the CPU clock. The present invention further comprises a Speedup circuitry to increase the CPU clock speed for enabled speedup events which are dependent on CPU clock speed.
