| Abstract: | Arithmetic coding is an attractive technique for lossless data compression but it tends to be slow. In this paper, a dynamic pipelined very large scale integration architecture with high performance for on-line adaptive binary arithmetic coding is presented. To obtain a high throughput pipelined architecture, we first analyze the computation flow of the coding algorithm and modify the operations whose data and/or control dependencies cause the difficulties in pipelining. Then, a novel technique called dynamic pipelining is developed to pipeline the coding process with variant (or run-time determined) pipeline latencies (or data initialization intervals) efficiently. As for data path design, a systematic design methodology of high level synthesis and a lower-area but faster fixed-width multiplier are applied, which implement the architecture with a little additional hardware. The dynamic pipelined architecture has been designed and simulated in Verilog HDL, and its layout has also been implemented with the 0.8-μm SPDM CMOS process and the ITRI-CCL cell library. Its simulated compression speeds under working frequencies of 25 and 50 MHz are about 6 and 12.5 Mb/s, respectively. About two times the speedup with 30% hardware overhead relative to the original sequential realisation is achieved. |
