摘要
根据H.264/JVT/AVC的最新要求,设计了一个有效的视频图像实时处理解块滤波的硬件结构和算法,使用具有可配置数据通道的8×4 8-b it移位寄存器来提供滤波器(并行输入,并行输出的FIR滤波器)所需要的水平和竖直方向上的数据,设计了两个SRAM片,一个用来存放当前图像数据,另一个用来存放相关联的数据.在0.25μm技术下的综合结果是:19.1 k门(不包含96×32和64×32的两个SRAM),100MHz.根据实际情况可以选择不同的滤波方式,解决了边缘上的像素点的不连贯问题,和软件实现解块滤波相比较,可以节约一半的带宽.
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. 8×48-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.
