ABSTRACT:
One embodiment of the present invention sets forth a technique for improving the flexibility and programmability of a graphics pipeline by enabling full access to integer texture maps within a graphics processing unit (GPU). A new mechanism for loading and unloading integer texture images is disclosed that enables the shader units within the GPU to have full access to integer values stored within an integer image buffer in a GPU local memory. New integer formats are added to the graphics API that indicate that data should be loaded and processed without the prior art conversion to a floating-point representation, thereby enabling the use of these new integer data types.
