Abstract: Systems and methods for switch prefetch in multicore computer chips can allow a programmer to tailor operations of a computer program to available data. Control-flow decisions can be made by the program based on the availability of data in a cache. For example, a new instruction in a processor instruction set can receive a list comprising pairs of data addresses and code addresses. The processor can look for data items corresponding to the listed data addresses, and find the first available data item in the cache. When a cached data item is found, control is transferred to the code address supplied in the table. If no data is in the cache, then the processor can stall until the most quickly fetched data item is available.

Abstract: A system for providing augmented reality detects foreground occluders in an image of a video stream. One or more virtual objects are then rendered appropriately with respect to the occluders. Location information associated with the image is used to retrieve a three dimensional representation of the location where the image was taken. Features that are expected to appear in the image based on the three dimensional location but that cannot be located are used to determine regions of the image that are likely to include foreground occluders. Pixels in these regions are used to train a color model that classifies pixels as either part of the background of the image or part of one or more foreground occluders. The pixels in the image are classified using the model, and one or more virtual objects are rendered so that they appear behind any foreground occluders.

Abstract: Systems and methods for scheduling thread execution among a plurality of processors based on evaluation of memory access data can comprise collecting and evaluating memory access data corresponding to two or more threads. Based on the evaluation results, it can be determined whether to prospectively assign the two or more threads to execute on different processors when they are to be executing simultaneously. A scheduler can select a processor to execute a thread, and consult an identity of threads to determine whether to assign them to the same or a different processor. The scheduler may also adjust a scheduling frequency for better thread compatibility on a single processor.
Abstract translation: 基于对存储器访问数据的评估在多个处理器之间调度线程执行的系统和方法可以包括收集和评估对应于两个或更多个线程的存储器访问数据。 基于评估结果，可以确定在要同时执行的情况下，是否将两个或更多个线程预先分配在不同处理器上执行。 调度器可以选择处理器来执行线程，并且查询线程的身份以确定是否将它们分配给相同或不同的处理器。 调度器还可以调整调度频率以在单个处理器上实现更好的线程兼容性。

Abstract: Network congestion avoidance within aggregated channels is disclosed. In one embodiment, a method first transmits a packet associated with a first channel of a plurality of related channels from a source protocol layer (e.g., a source IP layer) of a source through a network (e.g., the Internet). Next, the method triggers an ECN event by the packet at the network. Finally, at least one channel is determined to have decreased packets transmitted therethrough, in response to the triggering of the ECN event (e.g., based on a congestion pricing criteria).
