Abstract (in Japanese) (See Japanese page) 
(in English) In this paper, we’ll describe how we made the circuit volume decreased and computation time shorter to develop a low-power and high performance JPEG 2000 LSI. In DWT logic, the number of multiplier decreased by optimizing computational algorithm of the DWT and the quantity of SDRAM access decreased by means of limited size computation without tile boundary artifact. And also we made entropy computation optimized to realize high-speed codec. As the result, its SDRAM access is reduced to 1/6, and it is possible to encode or decode VGA (640x480 pixel) video 30 frames per second suitable for Motion JPEG 2000.
