High performance two-symbol arithmetic encoder in JPEG 2000
Yu-Wei Wayne Chang, Hung-Chi Fang, Liang‐Gee Chen · 2005
In JPEG 2000, the Arithrneric Encoder (AE) is the throiighpirt bottleneck. A n AE capahle of encoding mnltiple symho1.s per cycle i s an @cient way to increase the throitghput .for higli-i-esohiiion inluge. In this paper, a twosyinhol AE arcliitectiire is pi-oposed. which can encode two symmhu1.s percycle.
