چکیده
A litling based I-D Discrete Wavelet Transform (DWT) core is proposed. It is re-configurable for Y 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 hard\+ ired multiplier with coefficients represented in canonic signcd-digit (CSD) form. I t is a compact and efficient DWT core for the hardware implementation of JPEG2000 encoder.

A Block-Based Architecture for Lifting Scheme Discrete Wavelet Transform
Two-dimensional discrete wavelet transform (DWT) for processing image is conventionally designed by line-based architectures, which are simple and have low complexity. However, they suffer from two main shortcomings the memory required for storing intermediate data and the long latency of computing wavelet coefficients. This work presents a new block-based architecture for computing lifting-bas...

This paper presents a novel (low arithmetic unit count) hardware architecture for performing lifting-based JPEG2000's 513 Discrete Wavelet Transform (DWT). The architecture is built around parallel Shift-Accumulator Arithmetic Logic Units (ALUs) which can encode (with implicit embedded extension[S]) up to five levels of transformation. The proposed architecture, which consists of three adders, ...

Abstract : In this paper, we propose an architecture that performs both forward and inverse lifting−based discrete wavelet transform. Our architecture reduces the hardware requirement by exploiting the redundancy in the arithmetic operation involved in DWT computation. The proposed architecture does not require any extra memory to store intermediate results. The proposed architecture consists o...
