摘要： One embodiment of the present invention sets forth a method for accessing texture objects stored within a texture memory. The method comprises the steps of receiving a texture bind request from an application program, wherein the texture bind request includes an object identifier that identifies a first texture object stored in the texture memory and an image identifier that identifies a first image unit, binding the first texture object to the first image unit based on the texture bind request, receiving, within a shader engine, a first shading program command from the application program for performing a first memory access operation on the first texture object, wherein the memory access operation is a store operation or atomic operation to an arbitrary location in the image, and performing, within the shader engine, the first memory access operation on the first texture object via the first image unit.

摘要： A method for generating a texture buffer object configured for storing and manipulating texture data for graphics processing operations includes the steps of creating a buffer object configured to store the texture data, binding the buffer object to a texture buffer object, binding the texture buffer object to one of a plurality of texture targets included within a texture image unit, and binding a shader program to a processing unit within a graphics rendering pipeline. One advantage of the disclosed method is that, once a texture buffer object is bound as the target of a texture image unit, shader programs may read and/or write to the buffer object referenced by the texture buffer object, without having to rebind that texture buffer object.

摘要： One embodiment of the present invention sets forth a technique for performing a computer-implemented method that controls memory access operations. A stream of graphics commands includes at least one memory barrier command. Each memory barrier command in the stream of graphics command delays memory access operations scheduled for any command specified after the memory barrier command until all memory access operations scheduled for commands specified prior to the memory barrier command have completely executed.

摘要： One embodiment of the present invention sets forth a technique for performing low latency computation on a parallel processing subsystem. A low latency functional node is exposed to an operating system. The low latency functional node and a generic functional node are configured to target the same underlying processor resource within the parallel processing subsystem. The operating system stores low latency tasks generated by a user application within a low latency command buffer associated with the low latency functional node. The parallel processing subsystem advantageously executes tasks from the low latency command buffer prior to completing execution of tasks in the generic command buffer, thereby reducing completion latency for the low latency tasks.
