An FPGA-based wavelet transforms coprocessor

Although FPGA technology oflers the potential of designing high performance systems at low cost for a wide range of applications, its programming model is prohibitively low level requiring either4 dedicated FPGA-experienced programmer or basics digital design knowledge. To allow a signaUimage processing end-user to benefit from this kind of devices, the level of design abstraction needs to be raised, even beyond a Hardware Description Longuage level (e.g. VHDL). This approach will help the application developer to focus on signauimage processing algorithms rather than on low-level designs and implementations. This paper aims to present a framework for an FPGA-based coprocessor dedicated to Discrete Wavelet Transfonns (DWT). The proposed approach will help the end-user to generate FPGA configurations for DWT at a highest level wirhout any knowledge of the low-level design styles and architectures.
