Abstract

A new architecture of the 2-dimension discrete wavelet transform(2D-DWT) is implemented on the FPGA for the JPEG2000 still image coding system.The feature of the 2D-DWT has been analyzed and a straightforward 2-dimension transform algorithm is employed to built the architecture reducing the frequency of the memory read/write in traditional implementation.Meanwhile

the structure got the high through-put

four wavelet coefficients per clock

high parallelism and great performance improvement by the pipeline.Only(N/2) clock periods will be needed when processing a N×N image.Experimental result shows that the proposed architecture is suitable for the real-time image compression application.
