Summary: 
This paper presents an efficient VLSI architecture of biorthogonal (9,7)/(5,3) lifting based discrete wavelet transform that is used by lossy or lossless compression of JPEG2000. To improve hardware utilization of RPA (Recursive Pyramid Algorithm) implementation, we make the filter that is responsible for row operations of the first level perform both column operations and row operations of the second and following levels. As a result, the architecture has 66.7-88.9% hardware utilization. It requires 9 multipliers, 12 adders, and 12N line memories for NN image, which is smaller hardware complexity compared to that of other architectures with comparable throughput.
