This paper presents effective DSP implementation strategies for real-time JPEG2000 encoder system, an overlapped block transferring (OBT) for DWT and a pipelined processing of passes (PPP) for EBCOT Tier-1. The proposed OBT method can significantly improve the performance of the lifting algorithm for DWT by increasing the cache hit rate. Moreover the PPP method reduces the processing time of EBCOT Tier-1 by pipelined processing of the three coding passes of the same bit-plane. Experimental results show that Motion-JPEG2000 DSP system meets the common requirement of the real-time video coding [30 frames/s (fps)] and is proven to be a practical and efficient DSP solution.
