10.4 Texture as a Read Path

When using texture as a read path—that is, using the texturing hardware to get around awkward coalescing constraints or to take advantage of the texture cache as opposed to accessing hardware features such as linear

interpolation—many texturing features are unavailable. The highlights of this usage for texture are as follows.

• The texture reference must be bound to device memory with CUDABindTexture() or cuTexRefSetAddress().
