A novel VLSI architecture for multidimensional discrete wavelet transform (mD DWT) based on a systolic array is proposed. We divide the input mD image data into 2m independent data streams, and then simultaneously pipeline them into a multi-filter chip, and finally obtain 2m samples which are from different DWT subbands per clock cycles (ccs). The proposed architecture performs a decomposition of an N1×N2×...×Nm image in about N1N2...Nm/(2m-1) ccs and requires relatively lower hardware cost than previous architectures. Besides, the advantages of the proposed architecture include very simple hardware complexity, regular data flow and low control complexity.
