摘要： Systems and methods that optimize memory allocation in hierarchical and/or distributed data storage. A memory management component facilitates a compact manner of identifying approximately how often the memory chunk is being used, to promote efficient operation of the system as a whole. Each memory location can be changed based on the corresponding memory access that is determined through tracking of statistical usage counts of memory locations, and a comparison thereof with a threshold value.

摘要： A method for tile-based rendering of content. Content may be rendered in a memory region organized as multiple tiles. In scenarios in which content is generated in layers, for operations that involve compositing image layers, an order in which portions of the image are processed may be selected to reduce the aggregate number of memory accesses times, which in turn may improve the performance of a computer that uses tile-based rendering. An image may be processed such that operations relating to rendering portions of different layers corresponding to the same tile are performed sequentially. Such processing may be used in a computer with a graphics processing unit that supports tile-based rendering, and may be particularly well suited for computers with a slate form factor. An interface to a graphics processing utility within the computer may provide a flag to allow an application to specify whether operations may be reordered.

摘要： Memory management techniques that permit an executing process to store content in memory and later retrieve that content from the memory, but that also permit a memory manager to discard that content to address memory pressure. A process executing on a computing device may notify a memory manager of the computing device that first memory space allocated to the process contains first content that is available for discard. If the memory manager detects the computing device is experiencing memory pressure, the memory manager may address the memory pressure by selecting memory space available for discard and discarding the content of the memory space. Before a process reuses content made available for discard, the process may notify the memory manager of the intent to reuse and, in response, receive empty memory and an indication that the content was discarded or receive an indication that the content is still available for use.

摘要： Techniques for minimizing coprocessor “starvation,” and for effectively scheduling processing in a coprocessor for greater efficiency and power. A run list is provided allowing a coprocessor to switch from one task to the next, without waiting for CPU intervention. A method called “surface faulting” allows a coprocessor to fault at the beginning of a large task rather than somewhere in the middle of the task. DMA control instructions, namely a “fence,” a “trap” and a “enable/disable context switching,” can be inserted into a processing stream to cause a coprocessor to perform tasks that enhance coprocessor efficiency and power. These instructions can also be used to build high-level synchronization objects. Finally, a “flip” technique is described that can switch a base reference for a display from one location to another, thereby changing the entire display surface.

摘要： Computer-readable media, computerized methods, and computer systems for managing dynamic allocation of one or more protected memory segments for storing content of secure data are provided. Initially, the secure data is recognized as being carried by a media stream being communicated from a media-reading device. One or more protected target segments and protected target segments are instantiated, where these protected memory segments are protected from illicit access by hardware-based rules. Regions of hardware memory are dynamically allocated to hold these protected memory segments and the secure data is iteratively written thereto. The protected source segments are associating with the media stream based on a license attached thereto, while the protected target segments are associating with presentation devices based on a standard of output protection supported thereby. Accordingly, the protected source segments are mapped to the protected target segments according to whether the license encompasses the standard of the output protection.

摘要： A video memory manager manages and virtualizes memory so that an application or multiple applications can utilize both system memory and local video memory in processing graphics. The video memory manager allocates memory in either the system memory or the local video memory as appropriate. The video memory manager may also manage the system memory accessible to the graphics processing unit via an aperture of the graphics processing unit. The video memory manager may evict memory from the local video memory as appropriate, thereby freeing a portion of local video memory use by other applications. In this manner, a graphics processing unit and its local video memory may be more readily shared by multiple applications.

摘要： A visualization system may receive first data indicating a first occurrence of a first event. The first event may be associated with a first kernel at a first time. The second event may relate to a processor operation, a memory operation, a disk operation, and the like. The visualization system may receive second data indicating a second occurrence of a second event. The second event may be associated with a second kernel at a second time. The second event may relate to an operation of the second kernel. The first kernel may correspond to a central processing unit, and the second kernel may correspond to a graphic processing unit. The visualization system may provide, based on the first and second data, a human-perceptible representation of the duration between the first time and the second time. The visualization system may provide a timeline that represents the first data and the second data.
