  • Fly-by serial bus arbitration
    Patent number: 6711173
    Abstract: In a first embodiment, multi-speed concatenated packet strings are transmitted by a first node on a serial bus. To accommodate multi-speed packets, a speed signal is transmitted immediately prior to the packet. In a second embodiment, ACK-concatenation is used to allow a node to transmit a data packet immediately after transmitting an acknowledge signal on the bus. The data packet need not be related to the ACK packet. In a third embodiment, a node which receives a first data packet followed by a data end signal on a child port, concatenates a second data packet onto the first data packet during retransmission. The second data packet is also transmitted down the bus in the direction of the node which originally transmitted the first data packet.

  • Power management for computer systems
    Patent number: 6711691
    Abstract: Power management approaches for computer systems having one or more processors are disclosed. One power management approach provides hierarchical power management. The hierarchical nature of the power management provided by the invention has various levels of power management such that power consumption of the computer system is dependent upon the amount of work placed on the processing resources of the computer system. Another power management approach pertains to deterministic handshaking provided between a power manager and one or more controller units. The deterministic handshaking provides for more reliable and controllable transitions between power management states which have associated power management taking place in the controller units. The power management approaches are suitable for use with a single-processor computer system or a multi-processor computer system.

  • Run-time modules for dynamically adjusting computer operation
    Patent number: 6708332
    Abstract: Code module interfaces are provided which allow a user to adjust the functionality of a program at run-time. The code module interfaces (CMIs) can be selectively activated by a user at run-time. Then, the control software will call the CMIs at various instances, for example, at startup, after each state change in the control software, at idle time and when the control software has completed all of its tasks. Alternatively, when each CMI is loaded, it can specify at which state change(s) that CMI is to be called to increase speed of operation.

  • Apparatus and method for awakening bus circuitry from a low power state
    Patent number: 6708278
    Abstract: Apparatus and techniques for awakening bus circuitry from an inactive state as needed are described. The bus circuitry forms part of a computer system and is placed in the inactive state (i.e., shut down) when not needed so as to conserve power. The bus circuitry is associated with a bus and can be awakened out of the inactive state when certain bus events, including resume, connect or disconnect, occur on the bus. The invention is particularly advantageous for computing devices (e.g., portable computers, desktop computers, server computers) where it is desirous to shut down bus circuitry as well as other circuitry (e.g., microprocessor) when not needed so as to reduce power consumption.

  • Assigning meanings to utterances in a speech recognition system
    Patent number: 6704710
    Abstract: Assigning meanings to spoken utterances in a speech recognition system. A plurality of speech rules is generated, each of the of speech rules comprising a language model and an expression associated with the language model. At one interval (e.g. upon the detection of speech in the system), a current language model is generated from each language model in the speech rules for use by a recognizer. When a sequence of words is received from the recognizer, a set of speech rules which match the sequence of words received from the recognizer is determined. Each expression associated with the language model in each of the set of speech rules is evaluated, and actions are performed in the system according to the expressions associated with each language model in the set of speech rules.

  • Retrieval of services by attribute
    Patent number: 6701428
    Abstract: An automatic method and apparatus for providing services on a computer system. A set of services is established providing different functionality for the computer system. With each of the set of services an attribute is stored for identifying characteristics of the function of each of the set of services. Then, the first set of services can be retrieved by a first set of attributes which is specified irrespective of any locales which may be defined in the computer system. Thus, characteristics or attributes of most importance to a service may be used to describe it and used for retrieval of such services. The establishing of the first set of services includes building a structure which references each of the first set of services. Retrieving may include maintaining a reference to one of the services in the structure and iterating through the structure in order to retrieve a subsequent one of the services.

  • Color palette providing cross-platform consistency
    Patent number: 6697079
    Abstract: A method and system to provide a color palette which facilitates user selection of web-safe colors. In laying out the color palette, the extent of achromatic colors located within the color palette is determined. The achromatic colors are then arranged in one group on the palette, for instance in order of lightest to darkest. The non web-safe chromatic colors are then grouped together. From this grouping blends of the colors are created. Finally, the web-safe chromatic colors are grouped together. Blends with respect to the web-safe chromatic colors are created and then grouped on the color palette.

  • Method and apparatus for display image rotation
    Patent number: RE38471
    Abstract: A method and an apparatus for rotating images on a computer system is disclosed. The system includes a processor for accessing an image frame buffer using a set of CPU addresses, a memory for storing the frame buffer, a controller for directing the pixel data of the frame buffer to a display device using a set of controller addresses. The two sets of addresses are not necessarily the same. In fact, numerous advantages could be had from manipulating those two sets of addresses resulting in image rotation operations for the display device.
