In accordance with the latest information of H.264/JVT/AVC,this paper presents a useful design and algorithm on real-time deblocking filter manipulating visual signal.8×4 8-bit shift register which is could be installed data passage is used to offer the horizontal and vertical data needed by the filter(FIR filter which is featured of parallel input and output).There are two SRAM chip,one for storing present visual data,the other is for related data.The comprehensive result through the technology of 0.25 micron: 19.1K gateway(96×32 and 64×32chips are no included),100 MHz.Different filtering methods could be adopted respectively according to the condition.This design solved incoherent problem of marginal pixel.This electrocircuit could save one half broadband resource compared with software-applying deblocking filter.
