摘　　要：针对JPEG2000解码系统中的核心处理模块——离散小波逆变换(IDWT),提出了一种基于FPGA的多级小波逆变换的高速、实时的硬件解决方案。仿真验证表明本方案能够满足连续输入的数据进行实时处理的要求,并且所设计的系统具有功耗低、成本低等优点。In spite of its many advantages such as higher compression rate,multi-resolution format and progressive transmission shows decoding,JPEG2000 has not been widely used because of its high cost of implementation since it was proposed.This paper presents a solution to the high-speed and real-time hardware of multi-level IDWT based on FPGA in view of the kernel processing module——inverse discrete wavelet transform （IDWT） in JPEG2000 decoding system.Simulation shows that this solution can meet the requirement for real-time processing of continuous input of data.Besides,the system has the advantages of less consumption and lower cost.
