Hardware structure for realizing SVC macroblock-level algorithm

Abstract

The embodiment of the invention provides a hardware structure for realizing an SVC macroblock-level algorithm, and aims at improving the encoding efficiency. The hardware structure comprises a memory, an arbitration module, a data reading module, a prediction module and a data sending module, wherein the data reading module, the prediction module and the data sending module realize access to the memory through the arbitration module; the memory saves base layer data, and the data reading module, the prediction module and the data sending module access the memory simultaneously or non-simultaneously; the arbitration module is used for judging the reading and writing priority of the data reading module, the prediction module and the data sending module to the memory; the prediction module is used for carrying out luminance sampling interpolation operation and chroma sampling interpolation operation on the data read from the memory by the data reading module to obtain luminance and chroma prediction values; SAD of the prediction values with the luminance information of the current frame is calculated, and finally the prediction values are saved in the memory.
