摘要： A signal phase shifting circuit shifts the phase of an input signal, such as a STROBE signal, based on a reference signal, such as a CLOCK signal, to facilitate, for example, receiving of double data rate data. The signal phase shifting circuit includes a reference signal period dividing circuit having a feedback delay matching array operatively coupled to one of a plurality of voltage control delay lines. This signal phase shifting circuit also includes a variable delay circuit that provides a phase shifted output signal, such as a phase shifted STROBE signal, that includes a delay stage in a phase shifted output signal drive buffer coupled to the delay stage, such as a voltage control delay line. The feedback delay matching array includes a plurality of serially coupled buffer stages operatively coupled to compensate for delay variations associated with the phase shifted output signal drive buffer in the variable delay circuit.

摘要： A method and apparatus for mapping a linear address to a tiled address that reduces latency between retrieval of pages of data is accomplished when a video graphics processor receives a linear address from the central processing unit and determines whether the linear address is referencing a tiled surface, which is one of up to four portions of the memory. If so, the video graphics processor obtains parameters of the tiled surface. Having obtained the parameters, the video graphics processor determines a normalized linear address based on at least one of the parameters and the linear address. Having done this, the video graphics processor determines a band pointer of the tiled surface based on at least one of the parameters, the normalized linear address and a modular function. In essence, the band pointer points to a normalized initial address of a band of a tiled surface, which includes a plurality of bands. Having obtained the band pointer, the video graphics processor then determines a linear band offset based on the band pointer and at least one of the parameters. Next, a tiled band offset is determined based on the linear band offset. Finally, the tiled address is determined based on the tiled band offset, the band pointer, and at least one of the parameters.

摘要： Briefly, a method, apparatus and system for managing power corresponding to a differential serial communication link that has a link width defined for example by one or more lanes wherein the lanes are adapted to communicate clock recovery information in a data stream, determines, during normal operating conditions, such as conditions other than power on, reset or link fault conditions, a desired link width for the serial communication link and then changes the link width accordingly.

摘要： In a specific embodiment, a system for providing video is disclosed, the system having a system bus, which in one embodiment is an Advanced Graphics Port (AGP) bus. The system bus is connected to a data bridge, which is connected to a second and third AGP bus. Each of the AGP busses are connected to graphics processors. The bridge routes data requests from one graphics processor to the second graphics processor without accessing the system AGP bus based upon a memory mapping information stored in a routing table or a register set. In another aspect of the present invention, the bridge responds to initialization requests using attributes that may vary depending on the specific mode of operation. Another aspect of the present invention allows for conversion between various AGP protocol portions.

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.
