| Abstract(in English) | Discrete Wavelet Transform (DWT), that is used for Image compression on JPEG2000, makes theoretically less noises than Discrete Cosine Transform (DCT), that is used on traditional JPEG. However, the compression ratio of DWT is lower than DCT and the procces of computation requires high frequently memory access, so that DWT isn't suitable for embedded system. Hardware accelarator is effective to solve such problems. If we used only ASIC, it requires high costs and long development time. On the other hand, FPGA is used for easy prototyping for ASIC to try new design, although developing a prototype of large and complicated system, such like graphic processing, takes long time too. High-Level Synthesis is gathering attention as a solution for this problem. It automatically generates RTL through Standard ANSI-C so as to shorten developing time. In this paper, we implemented DWT that consists of Daubechies' wavelet using ImpulseC, the High-Level Syntheis Language for FPGAs. As a result, we achived approximatly 50 times faster result than software execution. |
