| Abstract(in English) | 2 Dimensional Discrete Wavelet Transform(2D-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 process of computation requires high frequently memory accesses, so that DWT is not suitable for embedded system. Hardware implementations of specific applications that have data transfer from host processor require certain implementation experience and prototyping to select a data transfer manner and an offload process. At the case of Prototype, FPGA is used to save cost and developing time. Although developing a prototype of large and complicated system takes long time itself. High-Level Synthesis Language being gathered 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 practical Line-Based Architecture 2D-DWT that consists of Daubechies' wavelet using Impulse C. As a result, we achieved approximately 5.29 times faster result than software execution. |
