In this paper, we have designed an LCD controller based on AMBA. Normally display systems using the LCD are adopted independent bus architecture for high speed data access. Proposed LCD controller complies with AMBA data format and has an image scaler that executes interpolation for full screen display. This image scaler employs FOI for horizontal scaling and H-Shape pseudomedian filter for vertical scaling. It has been designed with VHDL and verified on prototype board using Xilinx FPGA and LCD panel.
