System for HEVC (High Efficiency Video Coding) deblocking filtering

The invention relates to a system for HEVC (High Efficiency Video Coding) deblocking filtering. The system comprises a main control module, a cache module, a filtering module and a reconstruction RAM (Random Access Memory), the main control module controls the cache module to read and write in different stages, controls the filtering module to carry out deblocking filtering operation, and provides address information of a corresponding memory; the filtering module comprises an input cache module, a coding parameter calculation module, a filtering operation module, a filtering decision module and an output cache module; the input cache module is used for receiving and caching data of the reconstructed RAM; the coding parameter calculation module is used for calculating coding parameters transmitted from the reconstruction RAM; the filtering operation module is used for executing filtering operation of input pixels; the filtering decision module is used for selecting a filtering output result according to the b
