This paper presents a FPGA implementation of rate control system for JPEG2000. The input image is discrete wavelet transformed, and the wavelet coefficients are encoded by Tier1 coding with rate distortion estimation. During the process of the Tier1 coding, the bit rate for each code block is allocated and the bit stream is then truncated to produce the final bit stream. The Verilog HDL modules for the rate control system are designed, simulated and synthesized to Altera’s FPGA. The result shows that the architecture proposed in this paper is correct.
