摘要： A method for implementing a software-managed cache comprises determining an object identifier (ID) for each of a first set of objects of a plurality of objects resident in a local memory, to generate a first cache table, the first cache table comprising a plurality of entries. Each object comprises an object ID and an effective address. The method receives a request for an object, the request comprising an object ID. The method compares the received object ID with the entries in the first cache table. In the event the received object ID matches an entry in the first cache table, the method returns the matching entry in response to the request. In the event the received object ID does not match an entry in the first cache table, the method calculates an effective address in the local memory of the object associated with the object ID.

摘要： Scene model data, including a scene geometry model and a plurality of pixel data describing objects arranged in a scene, is received. A primary pixel color and a primary ray are generated based on a selected first pixel data. If the primary ray intersects an object in the scene, an intersection point is determined. A surface normal is determined based on the object intersected and the intersection point. The primary pixel color is modified based on a primary hit color, determined based on the intersection point. A plurality of ambient occlusion (AO) rays each having a direction, D, are generated based on the intersection point, P and the surface normal. Each AO ray direction is reversed and the AO ray origin is set to a point outside the scene. An AO ray that does not intersect an object before reaching the intersection point is included in ambient occlusion calculations. The primary pixel color is shaded based on the ambient occlusion and the primary hit color and an image is generated based on the primary pixel color for the pixel data.

摘要： A mechanism is provided for efficient communication of producer/consumer buffer status. With the mechanism, devices in a data processing system notify each other of updates to head and tail pointers of a shared buffer region when the devices perform operations on the shared buffer region using signal notification channels of the devices. Thus, when a producer device that produces data to the shared buffer region writes data to the shared buffer region, an update to the head pointer is written to a signal notification channel of a consumer device. When a consumer device reads data from the shared buffer region, the consumer device writes a tail pointer update to a signal notification channel of the producer device. In addition, channels may operate in a blocking mode so that the corresponding device is kept in a low power state until an update is received over the channel.

摘要： A method comprises receiving scene model data including a scene geometry model and a plurality of pixel data describing objects arranged in a scene. The method generates a primary ray based on a selected first pixel data. In the event the primary ray intersects an object in the scene, the method determines primary hit color data and generates a plurality of secondary rays. The method groups the secondary packets and arranges the packets in a queue based on the octant of each direction vector in the secondary ray packet. The method generates secondary color data based on the secondary ray packets in the queue and generates a pixel color based on the primary hit color data, and the secondary color data. The method generates an image based on the pixel color for the pixel data.

摘要： Scene model data, including a scene geometry model and a plurality of pixel data describing objects arranged in a scene, is received. A first pixel data of the plurality of pixel data is selected. A primary pixel color and a primary ray are generated based on the first pixel data. If the primary ray intersects an object in the scene, an intersection point, P is determined. A surface normal, N, is determined based on the object intersected and the intersection point, P. A primary hit color is determined based on the intersection point, P. The primary pixel color is modified based on the primary hit color. A plurality of ambient occlusion (AO) rays are generated based on the intersection point, P and the surface normal, N, with each AO ray having a direction, D. For each AO ray, the AO ray direction is reversed, D, the AO ray origin, O, is set to a point outside the scene. Each AO ray is marched from the AO ray origin into the scene to the intersection point, P. If an AO ray intersects an object before reaching point P, that AO ray is excluded from ambient occlusion calculations. If an AO ray does not intersect an object before reaching point P, that ray is included in ambient occlusion calculations. Ambient occlusion is estimated based on included AO rays. The primary pixel color is shaded based on the ambient occlusion and the primary hit color and an image is generated based on the primary pixel color for the pixel data.
