The paper presents the design and implementation of a soft decoder IP based on the JPEG image compression standard.The design adopts the IDCT algorithm architecture which is efficient for hardware implementation.In consideration of speed,a parallel and pipeline architecture is introduced.Based on the characteristic of Huffman code a new hardware structure of Huffman parallel decoding is introduced,replacing the complex pattern matching with the simple arithmetic operations,so that high decoding rate and low cost can be achieved.This IP can be conveniently integrated into various applications such as digital camera,cell phone,and color FAX.

Key words: JPEG;IP core;Huffman;pipelining design
