摘要： A circuit arrangement and method implement impulse propagation in a multithreaded physics engine by assigning ownership of objects in a scene to individual threads and propagating impulses between objects that are in contact with one another by passing inter-thread impulse messages between the threads that own the contacting objects, while locally propagating impulses through objects using the threads to which such objects are assigned.

摘要： A circuit arrangement and method utilize predictive load balancing to allocate the workload among hardware threads in a multithreaded physics engine. The predictive load balancing is based at least in part upon the detection of predicted future collisions between objects in a scene, such that the reallocation of respective loads of a plurality of hardware threads may be initiated prior to detection of the actual collisions, thereby increasing the likelihood that hardware threads will be optimally allocated when the actual collisions occur.

摘要： A method includes assigning a priority to a ray data structure of a plurality of ray data structures based on one or more priorities. The ray data structure includes properties of a ray to be traced from an illumination source in a three-dimensional image. The method includes identifying a portion of the three-dimensional image through which the ray passes. The method also includes identifying a slave processing element associated with the portion of the three-dimensional image. The method further includes sending the ray data structure to the slave processing element.

摘要： A method includes rendering an object of a three dimensional image via a pixel shader based on a render context data structure associated with the object. The method includes measuring a performance statistic associated with rendering the object. The method also includes storing the performance statistic in the render context data structure associated with the object. The performance statistic is accessible to a host interface processor to determine whether to allocate a second pixel shader to render the object in a subsequent three-dimensional image.

摘要： An apparatus, program product and method reuse static image data generated during rasterization of static geometry to reduce the processing overhead associated with rasterizing subsequent image frames. In particular, static image data generated one frame may be reused in a subsequent image frame such that the subsequent image frame is generated without having to re-rasterize the static geometry from the scene, i.e., with only the dynamic geometry rasterized. The resulting image frame includes dynamic image data generated as a result of rasterizing the dynamic geometry during that image frame, and static image data generated as a result of rasterizing the static image data during a prior image frame.

摘要： A computer-implemented method, system and computer program product for controlling an algorithm that is performed on a unit of work in a subsequent software pipeline stage in a Network On a Chip (NOC) is presented. In one embodiment, the method executes a first operation in a first node of the NOC. The first node generates payload, and then loads that payload into a message. The message with the payload is transmitted to a nanokernel that controls a second node in the NOC. The nanokernel calls an algorithm that is needed by a second operation in a second node in the NOC, which uses the algorithm to execute the second operation.
