摘要： A processor for use in a digital data processing system includes a data path which is controlled by microinstructions from the processor's control circuits. The data path includes a plurality of registers and an arithmetic and logic unit. The source data processed by the arithmetic and logic unit is obtained from the registers and elsewhere in the system as identified by selected fields of the microinstruction, and the processed data is stored in destinations also identified by the source selection fields or other locations. The destination selection field of the microinstruction selects a source identification or another destination as the selected destination.

摘要： A scheduler with admissions control in a continuous media file server. The scheduler supports multiple classes of tasks with diverse performance requirements. The scheduler is based on a combination of rate-monotonic and weighted round-robin scheduling schemes. Scheduling is accomplished in a hierarchical manner. Isochronous tasks have the highest priority and are scheduled first followed by real-time tasks and then general-purpose tasks. Isochronous tasks run periodically and are invoked by a timer interrupt set for each task. After scheduling the isochronous tasks, the scheduler alternates between the real-time tasks and the general-purpose tasks using a weighted round-robin scheme.

摘要： A software unit development and test methodology in which a software application or project is dividing into conceptual units. Each unit is first developed and debugged in an isolated testing environment which simulates the actual testing environment through test conditions. Following unit testing, other tested units are incrementally combined and tested in a similar isolated manner. Automatic generation of a testing environment and development system driving debugging and testing software, for measuring testing completeness, and for verifying correctness of future development and maintenance efforts are provided.

摘要： A processor for use in a digital data processing system including a main memory and one or more input/output units. The processor includes a cache memory. When the processor retrieves data, it may, in response to the condition of internal flags conditioned by the operating system, be stored in the cache. Even if the flags enable retrieved data to be cached, the main memory or input/output units may assert a signal which disables caching.

摘要： A technique for modifying the IEEE 802.3 standard for selecting backoff times in a Carrier Sense Multiple Access with Collision Detection (CSMA/CD) network, in the event that a collision is sensed by a node that has captured the network communication channel. If there is a small number of active nodes on the network, one node may capture the channel and the standard backoff algorithm makes it increasingly unlikely for another node to transmit. The new technique provides for less aggressive, i.e. longer, backoff times before at least the first retransmission attempt made by a node that has captured the channel. Three specific examples of the technique are disclosed. Even though the invention represents a departure from the standard CSMA/CD backoff algorithm, the overall average backoff times provided by the invention can be selected to be consistent with the average times provided by the standard. Moreover, nodes using the invention interoperate successfully with nodes that do not.
