標題: | Lifting based discrete wavelet transform architecture for JPEG2000 | 作者: | Lian, Chung-Jr Chen, Kuan-Fu Chen, Hong-Hui LIANG-GEE CHEN |
公開日期: | 2001 | 卷: | 2 | 起(迄)頁: | 445-448 | 來源出版物: | ISCAS 2001 - 2001 IEEE International Symposium on Circuits and Systems, Conference Proceedings | 會議論文: | 2001 IEEE International Symposium on Circuits and Systems, ISCAS 2001 | 摘要: | A lifting based 1-D discrete wavelet transform (DWT) core is proposed. It is re-configurable for 5/3 and 9/7 filters in JPEG2000. Folded architecture is adopted to reduce the hardware cost and achieve the higher hardware utilization. Multiplication is realized in hardwired multiplier with coefficients represented in canonic signed-digit (CSD) form. It is a compact and efficient DWT core for the hardware implementation of JPEG2000 encoder. © 2001 IEEE. |
