Abstract :
The architecture of a realtime wavelet video coder is described, with the main emphasis put on memory bandwidth reduction and efficient VLSI implementation. The proposed architecture adopts a modified 2-D subband decomposition scheme, alongside of a parallelized pipelined Embedded Zerotree Wavelet coder architecture. The video encoder is integrated in a 0.35 μm 3LM chip by using 341 K transistors on a 4.93×4.93 mm2 die, which can process 720×480 30 fps pictures in realtime
