Disclosed is a graphics processing unit comprising an instruction decoder and sum-of-absolute-differences (SAD) accleration logic. The instruction decoder is configured to decode a SAD instruction into parameters describing an M×N and an n×n pixel block in U,V coordinates. The SAD accleration logic is configured to receive the parameters and compute SAD scores. Each SAD score corresponds to the n×n block and to one block contained within the M×N pixel block and horizontally offset within the n×n block. Also disclosed is a GPU comprising a host processor interface receiving video acceleration instructions and a video acceleration unit. The unit is responsive to the instructions and comprises SAD accleration logic configured to receive the parameters and compute SAD scores. Each SAD score corresponds to an n×n pixel block and to one block contained within an M×N block and horizontally offset within the n×n block. M, N, and n are integers.

Systems and methods for border color handling in a graphics processing unit are disclosed. In one embodiment, the system includes a border color register that stores at least one border color pointer. A border color pointer indicates an address in an external memory at which border color information is located. Border color information is populated within external memory and retrieved by the texture cache controller if the texture filter unit requires a border color for texture mapping operations.

Disclosed herein is a graphics-processing unit (GPU) having an internal memory for general-purpose use and applications thereof. Such a GPU includes a first internal memory, an execution unit coupled to the first internal memory, and an interface configured to couple the first internal memory to a second internal memory of an other processing unit. The first internal memory may comprise a stacked dynamic random access memory (DRAM) or an embedded DRAM. The interface may be further configured to couple the first internal memory to a display device. The GPU may also include another interface configured to couple the first internal memory to a central processing unit. In addition, the GPU may be embodied in software and/or included in a computing system.
