The Hardware Acceleration Research of Image Zooming and Rotation Based on The Opt-shifting Bilinear Interpolation

The paper optimize the accuracy of the opt-shifting bilinear interpolation.Implementation uses the ARM A9 processor software fixed-point implementation than 13.5times floating point processing speed.Then the paper puts forward a highly efficient hardware implementation structure and implemented on Xilinx Zedboard.The experimental results show that in typical cases: hardware can 9times faster than implementation by the ARM A9 software fixed-point.
