초록
This paper proposes the optimized hardware architecture for a high performance image downscaler The proposed downscaler uses non-linear digital filters for horizontal and vertical scalings. In order to achieve the optimization, the filters are implemented with multiplexer-adder type scheme and all the filter coefficients are selected on the order of two's power. The performance of the scaler is also verified by comparing with a pixel drop downscaler. The proposed scaler is designed by using the VHDL and implemented by using the IDEC-C632 0.65
