    摘要： An improved method and apparatus for recognizing, classifying and processing frames received at a frame processor in a computer network is disclosed. Following receipt of a frame at an input port of a frame processor, source and destination addresses are parsed from the frame. A plurality of lookup tables are provided in a memory, each of which contains a search field and a classification key field. Source or destination addresses are stored in the respective search fields along with other information associated with the frame and a compact classification key is stored in the corresponding classification key field. Searches are performed of the respective search fields within the respective lookup tables to determine whether a match exists between the each of the destination and source addresses and other information and the search field within the lookup tables. In the event the searches yield a match, a classification key associated with each respective address is retrieved. Classification keys corresponding to addresses thus retrieved are concatenated and the concatenated value is employed as the basis for a further search of the search field of another one of the lookup tables to identify a classification key which is employed to specify the manner of further processing of the received frame.

    摘要： A Blended Wing Body SUAV and MUAV is disclosed having a novel airfoil profile, wing configuration, rigging and tractor pull propeller placement that provide improved stability and safety characteristics over prior art SUAVs and MUAVs of comparable size and weight. This unique blended wing design includes wing twist on the outboard wing and an inverted “W” shaped planform to provide lateral and longitudinal stability, and smooth, even flight characteristics throughout the range of the expected flight envelope. These flight characteristics are crucial to providing a stable reconnaissance platform with favorable stall speeds, an increased payload and the ability to hand launch without the danger of exposing ones hands or wrist to a propeller.

    摘要： A command queuing engine in a target controller ASIC automatically detects sequential commands received from an initiator and generates a linked list of data transfer descriptors for the sequential commands. The data transfer descriptors are automatically processed by the command queuing engine to reduce command overhead from interrupt processing by a microprocessor in the target controller, thereby improving the performance of the target controller.

    摘要： Described embodiments provide a host subsystem that generates a host context corresponding to a received host data transfer request. A programmable sequencer generates one or more sequencer contexts based on the host context. Each of the sequencer contexts corresponds to at least part of the host data transfer request. The sequencer contexts are provided to a buffer subsystem of the media controller. For host read requests, the buffer subsystem retrieves the data associated with the sequencer contexts of the read request from a corresponding buffer or a storage media and transmits the data associated with the sequencer contexts to the host device. For host write requests, the buffer subsystem receives the data associated with the host context from the host device and stores the data associated with the sequencer contexts of the write request to a corresponding buffer or the storage media.

    摘要： The disk drive provides a method of adaptively managing a cache segment divided into chunks by defining an unavailable data type to be stored in an element of a chunk array which indicates that the chunk is not available, and defining an available data type to be stored in an element of the chunk array that indicates the chunk is available and that indicates the number of consecutive chunks that are available. The disk drive also computes a number of chunks needed to fit the request length and scans the chunk array to find a first available element whose available data type meets a predetermined criteria for the number of chunks needed to fit the request length.

    摘要： A magnetic disk drive with a caching system includes an intelligent interface to communicate with a host, a magnetic disk and a cache memory to buffer data transferred to and from the host. The caching system maximizes drive performance based on past access history. The caching system alters execution of commands by coalescing commands or executing internal commands in parallel. The caching system anticipates data requests by using a prefetch to store data that may be requested. The caching system divides the cache memory into segments to store multiple streams of data. The number of segments may be continuously adapted according to the types of access to maximize performance by maintaining a segment for each sequential stream of data. The caching system uses a dynamic priority list to determine segments to maintain and discard. Each segment is monitored to determine access types such as sequential, random, and repeating. The access type determines the amount of data to prefetch and to save, including a minimum and maximum prefetch. The caching system may prescan the cache memory during prefetch to alter the prefetch amount in response to a command request. The caching system may wait for a cache memory access that has not yet occurred. An initiator changes the caching parameters though a mode page.

    摘要： A computer system of the type having a processor section, a memory section, an input-output section, a system clock, and a system bus for communicating signals between the sections, accommodates a variable number of processor units in the processor section. The processor section hence is expandable. Synchronization is distributed in that each processor unit can synchronize all the units in the processor section. The processor units arbitrate for access to the system bus, and respond to interrupts, on a distributed basis. A distribution counter in each processor unit provides a periodically sequencing unique count to distribute tasks among the processor units.
