Popis: This paper presents a parallel architecture for the Embedded Block Coding (EBC) in JPEG 2000. The architecture is based on the proposed word-level EBC algorithm. By processing all the bit planes in parallel, the state variable memories for the context formation (CF) can be completely eliminated. The length of the FIFO (first-in first-out) between the CF and the arithmetic encoder (AE) is optimized by a reconfigurable FIFO architecture. To reduce the hardware cost of the parallel architecture, we proposed a folded AE architecture. The parallel EBC architecture can losslessly process 54 MSamples/s at 81 MHz, which can support HDTV 720p resolution at 30 frames/s.
