  • Publication number: 20190050149
    Abstract: Techniques for controlling access to a memory are provided. The techniques may include receiving and storing output pixel data in a buffer, providing the stored output pixel data to a display controller, receiving stored output pixel data from the buffer at the display controller, switching to a second operating mode state based at least on an amount of available data in the buffer being less than or equal to a threshold, identifying a portion of the image data stored in a memory device for use in generating output pixel data for an updated image, and, in response to operating in the second operating mode, generating the output pixel data without issuing a memory read command via an interconnect to retrieve the portion of the initial image while operating in the second operating mode, and providing the output pixel data to the buffer.

  • Publication number: 20180322688
    Abstract: Systems and methods for multistage post-rendering image transformation are provided. The system may include a transform generation module arranged to dynamically generate an image transformation. The system may include a transform data generation module arranged to generate first and second transformation data by applying the generated image transformation for first and second sampling positions and storing the transformation data in a memory. The system may include a first image transformation stage that selects the first and second transformation data for a destination image position and calculates an estimated source image position based on the selected first and second transformation data.

  • Patent number: 10095408
    Abstract: Systems and methods for controlling access to a memory are provided. The system may include a buffer to store output data generated by a processing module, and provide the output data to a real-time module, and a buffer monitoring circuit to output an underflow approaching state indication in response to an amount of available data in the buffer being less than or equal to a threshold. The system may include a memory access module arranged to receive memory requests issued by the processing module, and configured to, while operating in a first mode, respond to memory requests with corresponding data retrieved from the memory, switch to operating in a second mode in response to receiving the underflow approaching state indication, and in response to operating in the second mode, respond to memory requests indicating the memory access module did not attempt to retrieve corresponding data from the memory.

  • Publication number: 20180275748
    Abstract: Optimizations are provided for late stage reprojection processing for a multi-layered scene. A multi-layered scene is generated. Late stage reprojection processing is applied to a first layer and different late stage reprojection processing is applied to a second layer. The late stage reprojection processing that is applied to the second layer includes one or more transformations that are applied to the second layer. After the late stage reprojection processing on the various layers is complete, a unified layer is created by compositing the layers together. Then, the render the unified layer is rendered.

  • Publication number: 20180276824
    Abstract: Optimizations are provided for late stage reprojection processing for a multi-layered scene. A scene is generated, which is based on a predicted pose of a portion of a computer system. A sub-region is identified within one of the layers and is isolated from the other regions in the scene. Thereafter, late stage reprojection processing is applied to that sub-region selectively/differently than other regions in the scene that do not undergo the same late state reprojection processing.

  • Patent number: 9047116
    Abstract: An apparatus, program product and method initiate, in connection with a context switch operation, a prefetch of data likely to be used by a thread prior to resuming execution of that thread. As a result, once it is known that a context switch will be performed to a particular thread, data may be prefetched on behalf of that thread so that when execution of the thread is resumed, more of the working state for the thread is likely to be cached, or at least in the process of being retrieved into cache memory, thus reducing cache-related performance penalties associated with context switching.

  • Patent number: 7739477
    Abstract: Page size prediction is used to predict a page size for a page of memory being accessed by a memory access instruction such that the predicted page size can be used to access an address translation data structure. By doing so, an address translation data structure may support multiple page sizes in an efficient manner and with little additional circuitry disposed in the critical path for address translation, thereby increasing performance.

  • Patent number: 7617499
    Abstract: An apparatus, program product and method initiate, in connection with a context switch operation, a prefetch of at least one instruction likely to be executed by a thread prior to resuming execution of that thread. As a result, once it is known that a context switch will be performed to a particular thread, one or more instructions may be prefetched on behalf of that thread so that when execution of the thread is resumed, those instructions are more likely to be cached, or at least in the process of being retrieved into cache memory, thus enabling a thread to begin executing instructions more quickly than if the thread was required to fetch those instructions upon resumption of its execution.
