Abstract
A video processing apparatus implemented in a chip includes an on-chip prediction buffer and a processing circuit. The on-chip prediction buffer is shared by a plurality of coding tools for prediction, and is used to store reference data. The processing circuit supports the coding tools for prediction, reads a plurality of first reference data from the on-chip prediction buffer as input data of a first coding tool that is included in the coding tools and enabled by the processing circuit, and writes output data of the first coding tool enabled by the processing circuit into the on-chip prediction buffer as a plurality of second reference data.
