in addition, only one edge filter is used for both vertical filtering and horizontal filtering in our design by proper data storage and attemper, this reusing strategy reduces the resource cost.
另外,通过适当的数据存储和调度使得水平边界滤波和垂直边界滤波复用一个一维滤波器,也降低了资源开销。
an embedded fifo architecture for vertical filtering in digital video processing is proposed, which can write in and read out several lines of data simultaneously.
