A reconfigurable frame interpolation hardware architecture for high definition video

Abstract

Since Frame Rate Up-Conversion (FRC) is started to be used in recent consumer electronics products like High Definition TV, real-time and low cost implementation of FRC algorithms has become very important. Therefore, in this paper, we propose a low cost hardware architecture for realtime implementation of frame interpolation algorithms. The proposed hardware architecture is reconfigurable and it allows adaptive selection of frame interpolation algorithms for each Macroblock. The proposed hardware architecture is implemented in VHDL and mapped to a low cost Xilinx XC3SD1800A-4 FPGA device. The implementation results show that the proposed hardware can run at 101 MHz on this FPGA and consumes 32 BRAMs and 15384 slices.
