摘要： Graphics generated by one graphics processor are transferred across a high speed interconnect bus to a frame buffer. The rendered frames from the frame buffer are presented on a display by way of a display interface in communication with the frame buffer. The display interface of another existing (e.g. integrated) graphics adapter/subsystem may be used to present the rendered frames on an interconnected display.

摘要： The present application discloses a method for communicating between at least two different levels of software components. The method includes establishing a command set common to the at least two different levels of software components. Additionally, the method includes providing a command decoder operable by both of the at least two levels of software components, the command decoder configured to decode the command set. By providing a common command set between different levels of software components, such as a software driver and a BIOS, where the commands within the command table are interpreted and executed by an identical command decoder that interprets and executes the same command tables, this ensures that the same features or functions are implemented or executed in the same way across different levels of the software components. Accordingly, redundant implementation of the same functions by different software components is eliminated. Additionally, when modification of the BIOS, for example, is performed, this modification only needs to be done in one place (i.e., the command table) rather than in each software component.
摘要翻译：本申请公开了一种用于在至少两个不同级别的软件组件之间进行通信的方法。该方法包括建立至少两个不同级别的软件组件共同的命令集。此外，该方法包括提供由至少两个级别的软件组件可操作的命令解码器，命令解码器被配置为对命令集进行解码。通过在不同级别的软件组件（例如软件驱动程序和BIOS）之间提供通用命令集，其中命令表中的命令由解释和执行相同命令表的相同命令解码器解释和执行，这确保了以相同的方式在不同级别的软件组件中实现或执行相同的特征或功能。因此，消除了不同软件组件对相同功能的冗余实现。此外，例如，当执行BIOS的修改时，该修改仅需要在一个地方（即，命令表）而不是在每个软件组件中完成。

摘要： In a door unlocking method that is to be implemented using an anti-theft device of an automobile, a predetermined time period and a predetermined count value are defined. When an interior door lock operates in the locking mode and when the anti-theft device is armed, shaking movements of the automobile are detected. When the detected shaking movements within the predetermined time period match the predetermined count value, the interior door lock is enabled to operate from the locking mode to the unlocking mode, and the anti-theft device is simultaneously disarmed.

摘要： An apparatus and method utilizes system memory as backing stores so that local graphics memory may be oversubscribed. Surfaces may be paged in and out of system memory based on the amount of usage of the surfaces. The apparatus and method also prioritizes surfaces among different tiers of local memory (e.g. frame buffer), non-local memory (e.g. page locked system memory), and system memory backing stores (e.g. pageable system memory) locations based on predefined criteria and runtime statistics relating to the surfaces. As such, local memory may be, for example, expanded without extra memory costs such as adding a frame buffer memory to allow graphics applications to effectively use more memory and run faster.

摘要： Embodiments of a system and method for handling interrupts are described herein. In an embodiment interrupts from various client components in a system (also referred to as clients) are processed by an interrupt handler component uniformly. The various clients signal interrupts in different manners. For example, some clients signal interrupts in a level-based manner, and some clients signal interrupts in a pulse-based manner. In an embodiment, all interrupts received by the interrupt handler are formed into an event message according to a uniform format regardless of the manner in which the interrupt is signaled. The event message includes all information necessary for a host processor interrupt service routine (ISR) to service the interrupts without reading hardware registers. Event messages are stored in an event buffer for access and handling by the host. The event buffer is managed by the interrupt handler.
摘要翻译：本文描述了用于处理中断的系统和方法的实施例。在一个实施例中，由系统中的各种客户端组件（也称为客户端）的中断由中断处理程序组件均匀地处理。各种客户端以不同的方式发出中断信号。例如，一些客户端以基于电平的方式发送中断，并且一些客户端以基于脉冲的方式发送中断。在一个实施例中，中断处理程序接收到的所有中断都是根据均匀的格式形成事件消息，而不管中断信号的方式如何。事件消息包括主机处理器中断服务程序（ISR）在不读取硬件寄存器的情况下服务中断所需的所有信息。事件消息存储在事件缓冲区中以供主机访问和处理。事件缓冲区由中断处理程序管理。

摘要： An efficient method of compositing planes onto a target surface using a computing device with graphics processing capability is disclosed. The method includes partitioning the target surface, on which planes are composited, into partitions. Each one of the partitions contains connected pixels to be formed by compositing an identical subset of the planes to be composited. Each partition is associated with a corresponding subset of the planes. Each partition and its corresponding set of associated planes are then provided to a graphics processor for composition, using exemplary software components including an application programming interface, a library and device driver software. An image is formed on the target surface by compositing each partition. Using the disclosed method, a single pass through stages of the graphics pipeline for the graphics processor is sufficient to composite multiple planes to form an image on the target surface.
