The Specifications of the Digital Cinema system released by Digital Cinema Initiatives decide to encode so-called 2K or 4K images by JPEG 2000. The JPEG 2000 codec provides high compression rates and error tolerance, but this codec is burden for both encoding and decoding. The parallel computing architecture named CUDA receives a lot of attention recently. In this paper, we attempt to realize real-time implementation of the two dimensional discrete wavelet transform (2D-DWT) of JPEG 2000 by using the newest developmental environment CUDA 4.0.
