摘要
设计一种自适应去块滤波器的硬件实现方法,采用垂直滤波和水平滤波交叉的处理顺序,通过使用寄存器组进行转置和存储中间数据,极大减小了访问带宽和片上存储资源,通过有效的控制机制实现了在289个时钟周期内对单一宏块数据进行去块滤波,可满足高清视频实时编码的需要。
A hardware-based implementation of an adaptive deblocking filter is proposed. It employs a new filter processing in turns of vertical boundaries inserted with horizontal boundaries and uses register array to transpose and store intermediate dates. As a result, it will greatly decrease the accessing bandwidth and memory resource on chip. With effective controlling mechanism, it will only take 289 clock cycles to filter each macroblock, and this design satisfies the requirement of real-time encoder of high definition video.
