Area efficient architecture for the embedded block coding in JPEG 2000
An area efficient architecture for the embedded block coding is presented in this paper. A new algorithm is proposed to compute the state variables on-the-fly. Thus, the memory for the state variables are eliminated, which occupies more than 60% area in a conventional embedded block coding architecture. The area of the proposed architecture is only 1/6 of conventional architectures while the throughput is the same as others. The proposed architecture has the highest performance comparing with other existing architectures according to the experimental results.
