    Abstract: The amount of memory required for code-block is one of the most important issues in JPEG2000 encoder chip implementation. This work tries to unify the output scanning order of the 2D-DWT and the processing order of the EBCOT and further to eliminate the code-block memory completely eliminated. We also propose a new architecture for embedded block coding (EBC), code-block switch adaptive embedded block coding (CS-AEBC), which can skip the insignificant bit-planes to reduce the computation time and save power consumption. Besides, a new dynamic rate distortion optimization (RDO) approach is proposed to reduce the computation time when the EBC processes lossy compression operation. The total memory required for the proposed JPEG2000 is only 2KB of internal memory, and the bandwidth required for the external memory is 2.1 B/cycle.
