JPEG2000，新一代的靜態影像壓縮技術，相較於JPEG，JPEG2000壓縮表現更為出色。然而，其計算複雜度遠高於JPEG。

在本論文中，我們提出一個有效率的EBC編碼架構，針對JPEG2000最複雜的位元平面編碼，本架構可以僅對平面掃瞄一次即完成編碼，如此一來處理速度便可大幅提升。此外，為了易於硬體實作，邏輯閘數目以及記憶體需求也經過縮減。

JPEG2000 is the new international standard for still image compression. It provides superior performance in terms of visual quality and PSNR compared to JPEG. However, the computational complexity of JPEG2000 is much higher than JPEG.

In this thesis, we present a efficient embedded block coding architecture for JPEG2000. For the fractional bit-plane coding, the most complicated part of JPEG2000, the architecture can process a bit-plane within one scan. This greatly improve the processing rate. Moreover, The gate counts and memory requirement are also reduced for hardware implementation.
