Abstract: Systems and methods for evaluating whether there is a collision between a first object represented by a first bounding volume and a second object represented by a second bounding volume, the method comprising determining at least one internal shape contained within the first bounding volume, and determining that there is an intersection between the at least one internal shape and the second bounding volume to conclude that there is a collision between the first object and the second object. Other aspects relate to systems and methods for filtering a plurality of candidate poses between first second objects.

Abstract: Selection logic can be used to select between a set of cache lines that are candidates for eviction from a cache. For each cache line in the set of cache lines, a relative probability that the cache line will result in a hit can be calculated based upon: past reuse behavior for the cache line; and hit rates for reuse distances. Based upon the relative probabilities for the set of cache lines, a particular cache line can be selected from the set of cache lines for eviction.

Abstract: The latencies associated with retrieving instruction information for a main thread are decreased through the use of a simultaneous helper thread. The helper thread is a speculative prefetch thread to perform instruction prefetch and/or trace pre-build for the main thread.

Abstract: Embodiments of an apparatus, system and method enhance the efficiency of processor resource utilization during instruction prefetching via one or more speculative threads. Renamer logic and a map table are utilized to perform filtering of instructions in a speculative thread instruction stream. The map table includes a yes-a-thing bit to indicate whether the associated physical register's content reflects the value that would be computed by the main thread. A thread progress beacon table is utilized to track relative progress of a main thread and a speculative helper thread. Based upon information in the thread progress beacon table, the main thread may effect termination of a helper thread that is not likely to provide a performance benefit for the main thread.

Abstract: Methods and an apparatus for generating a speculative helper thread for cache prefetch are disclosed. The disclosed techniques select spawn-target pairs based on profile data and a series of calculations. Helper threads are then generated to launch at the selected spawn points in order to prefetch software instructions (or data) for a single-threaded software application. The generated helper threads are then attached to the single-threaded software application to create a multi-threaded software application.
