High speed interpolator with fast adder
Thara Paul, Riboy Cheriyan · 2014
Here, proposed a high performance interpolator with different type of fast adder. High speed interpolator consists of a combined filter and a bilinear interpolator. A combined filter is made by using Sharpening spatial filter and clamp filter. Combined filter is the combination of T shaped and inversed T shaped model Filters. In order to reduce the memory requirement the combination of T and inverse T model convolution kernels are used. A reconfigurable calculation unit is presented to minimize the hardware cost of the combined filter. Kogge-stone adder is used to improve the speed of operation. Kogge-stone adder is faster than ripple carry adder. The proposed system requires only one-line memory buffer.
