FPGA-Based Discrete Wavelet Transforms System

Although FPGA technology offers the potential of designing high performance systems at low cost, its programming model is prohibitively low level. To allow a novice signal/image processing end-user to benefit from this kind of devices, the level of design abstraction needs to be raised. This approach will help the application developer to focus on signal/image processing algorithms rather than on low-level designs and implementations. This paper presents a framework for an FPGA-based Discrete Wavelet Transform system. The approach helps the end-user to generate FPGA configurations for DWT at a high level without any knowledge of the low-level design styles and architectures.
