Abstract

A video processing system with reconfigurable instructions includes a processor, a first register file in the processor, an extension adapter, programmable logic, a second register file coupled to the programmable logic, and a load/store module. The processor executes a video application that contains an instruction extension not native to the instruction set of the processor. The extension adapter detects the instruction extension in the video application. The programmable logic device is configured to execute the instruction extension. The programmable logic device then executes the instruction extension. The load/store module transfers data between the first register file and the second register file, and transfers data directly between the second register file and a system memory for use by the processor in processing the video application.
