碩士 === 國立臺灣大學 === 電機工程學研究所 === 90 === JPEG2000 system is the newest standard for still image compression. In this Thesis, we discuss the basic architecture of JPEG2000 system, which could be viewed as an evolution of image compression techniques during recent years. However, the key component, which is called “EBCOT,” contains many bit-level computation and multiple scan, it makes JPEG2000 too slow to fit some applications if we use general purpose CPU to execute JPEG2000. We design and implement an ASIC to accrete EBCOT, the cycles needed are reduced to about 45% of the original algorithm, and the clock rate can reach 133MHz in our simulation.
