In this paper, a digital image watermarking system compiled by the LDPC code is introduced to embed and extract the image watermark. The system software is realized by the mixed programming with Matlab and Qt at first. It could get real-time input data for the LDPC decoder. Then the hardware of the LDPC decoder is primarily implemented by FPGA in the digital image watermarking system. And the serial port is used to make the output data of the decoder back to computer for verification. Through the simulation results, the Models time simulation diagram is given, and the watermark image compared with the original image is got. The results show that the resource usage of our system is few, and the decoding rate is fast. It has a certain practical value.
