Abstract :
We present a hardware JPEG2000 decoder architecture based on the DCI specification, which can decode digital cinema frames without accessing any external memory. Besides, an innovative method is proposed to implement decoding process in accordance with the order of output images rather than sequentially to the input code-stream. In this way, not only can the decoded images be outputted immediately, but the storage resources for those middle states and temporary image data can be obviously reduced.
