Abstract
This paper presents a hardware implementation of an adaptive modelling unit for parallel binary arithmetic coding. The presented model combines the advantages of binary arithmetic coding where the coding process is simplified, with the benefits of multi-alphabet arithmetic coding where any type of data can be compressed. The modelling unit adopts a simple method to store and modify the information, making it able to process 8 bits per clock cycle and to increase substantially the arithmetic coding speed. This model has been implemented in an A500K130 ProASIC FPGA and offers a throughput of 256 Mbits/s.
