摘要： A system and method for injecting hardware errors into a microprocessor system is described. In one embodiment, a software interface between system software and system firmware is established. Software test and debug for software error handlers may thus be supported. The software interface may support both a query mode call and a seed mode call. When a query mode call is issued, it may request whether or not the system firmware and hardware support the injection of a specified kind of error. A return from this call may be used to make a list of supported errors for injection. When a seed mode call is issued, the corresponding error may be injected into the hardware.

摘要： Timing calculator means in a computer system are used to adaptively generate an appropriate access signal, to one of a plurality of memory types, based on first and second timing control values, wherein the first timing control value represents information specific to and limited to the start of a memory operation and wherein the second timing control value represents information representing other timing events. That is, the state machine of the present invention requires a distinct starting control value, separate from other timing values, for calculation of appropriate memory access parameters.

摘要： In a computer system having an audio circuit and networking circuit for data conferencing with an external network, a method of configuring the computer system for data conferencing includes the step of storing a plurality of data conferencing protocols. The method then determines which one of the plurality of data conferencing protocols is needed for the computer system for data conferencing. The computer system is then configured in accordance with a first protocol of the plurality of data conferencing protocols if the computer system is determined to require the first protocol for data conferencing. The method then selects an audio device driver and a networking device driver that correspond to the first protocol from a plurality of audio and networking device drivers for controlling operations of the audio and networking circuits. A communication link is established between the audio and networking device drivers for directly transferring digitized audio data between the audio and networking device drivers without via an interfacing operating system during data conferencing such that transmission latency of the digitized audio data is minimized. A computer system for data conferencing is also described.

摘要： A method and apparatus for sharing a logic block between multiple peripheral/input/output I/O devices. A method and apparatus for generating a first interrupt in response to a request from one of the devices. A second interrupt is also generated. The second interrupt is recognized before the first interrupt, such that the second interrupt is handled first and causes the logic block to be configured for the requested device. Then the first interrupt is then handled in which the request to the desired device is serviced using the reconfigured hardware.

摘要： A power management mechanism for use in a computer system having a bus, a memory for storing data and instructions, and a central processing unit (CPU). The CPU runs an operating system having a power management virtual device driver (PMVxD) responsible for performing idle detection for devices. The PMVxD performs idle detection using event timers that provide an indicator as to the activity level. The PMVxD places idle local devices in a reduced power consumption state when no activity has occurred for a predetermined period of time.
