摘要

在JPEG2000标准中，离散小波变换被用作静态图像压缩的前向变换。提出了一种高效的VLSI架构，并对其性能进行了评估，并与先前提出的架构进行了比较。该架构在两种不同类型的FPGA芯片上进行了功能仿真和综合，设计统计和动态性能(最大开关频率)证明是切实可行的。

Realization of an efficient VLSI architecture for discrete wavelet transform in real time image compression

The discrete wavelet transforms is used as a forward transform in the JPEG2000 standard for still image compression. An eflcient VLSI architecture is presented and its performance is evaluated and compared to the previously proposed architectures. This architecture is functionally simulated and synthesized on two dserent types of FPGA chips, the design statistics and dynamic performance (maximum switching frequency) turned out to be practically feasible.
