Abstract : The image compression standard JPEG2000 proposes a large set of features, useful for today's multimedia applications. Unfortunately, its complexity is greater than older standards. A hardware implementation brings a solution to this complexity for real-time applications, such as Digital Cinema. In this paper, a decoding scheme is proposed with two main characteristics. First, the complete scheme takes place in an FPGA without accessing any external memory, allowing integration in a secured system. Secondly, a customizable level of parallelization allows to satisfy a broad range of constraints, depending on the signal resolution.
