Granted: 1999-10-05
Abstract: An interrupt driven peripheral controller (103) for use in an Industry Standard Architecture (ISA) compatible computer provides a system to minimize power consumption as compared to conventional peripheral controllers. The peripheral controller (103) utilizes an internal interrupt controller (110) which responds to inputs from an ISA compatible microprocessor host (102), a keyboard (112), a mouse, and other devices connected to the I/O ports of the ISA compatible computer. The interrupt controller (110) provides an interrupt register for the peripheral controller (103) and generates an interrupt any time one or more of the devices controlled by the peripheral controller (103) is activated. The peripheral controller (103) enters a low power consumption mode if no interrupts are detected for a predetermined period of time. When the interrupt controller (110) generates an interrupt, the peripheral controller (103) is activated from its low power mode and services the device or devices which have caused the interrupt.

Granted: 1999-02-16
Abstract: A wide variety of call traffic is effectively integrated in a single broadband communications network. Calls having widely differing bandwidth requirements and sensitivities to delay are handled by the network with efficient, effective, and fair bandwidth allocation and transmission scheduling. This is accomplished by classifying each call in accordance with certain signal characteristics, such as required bandwidth and sensitivity to delay. Each call class is directed to a separate queuing circuit. Some calls in certain classes, such as those associated with high-bandwidth constant bit rate services, are each directed to their own individual queuing circuits. Other calls within a class are statistically multiplexed into a single queuing circuit for that class. A multiplexing circuit operates in accordance with a dynamic time slice scheme which involves defining a service cycle time period during which the multiplexer withdraws a predetermined number of information packets from each of a plurality of queuing circuits containing information packets and places those predetermined numbers of packets onto an output link. The multiplexer breaks up the cycle time period into a plurality of time slices, each of which determines how many information packets are transmitted from each queuing circuit during the cycle time period. Efficient resource usage and congestion avoidance are further achieved by using one of a number of alternative scheduling techniques for delay insensitivetraffic.

Abstract: An interrupt subsystem within a data processing system is scalable from low-end uni-processor systems to high-end multi-processor (MP) systems.  This interrupt subsystem provides for queueing of interrupts from many sources, and for queueing of interrupts to the best processor in a multi-processor system. The external interrupt mechanism is separated into two layers, an interrupt routing layer and an interrupt presentation layer.   The interrupt routing layer routes the interrupt conditions  to  the  appropriate  instance  of  an  interrupt management area within the interrupt presentation layer.  The interrupt presentation layer communicates the interrupt source to  the  system  software  which  is  to  service/process  the interrupt.  By providing two  layers  within the  interrupt subsystem, application or system software can be written which is independent from the types or sources of interrupts. The interrupt routing layer hides the details of a particular hardware  implementation from the  software.  The  interrupt presentation layer interfaces to the system and/or application software, and provides hardware independent functionality.
