Implementation of JPEG2000 arithmetic decoder using dynamic reconfiguration of FPGA

2005

This paper describes implementation of a part of JPEG2000 algorithm (MQ-Decoder and arithmetic decoder) on a FPGA board using dynamic reconfiguration. Comparison between static and dynamic reconfiguration is presented and new analysis criteria (time performance, logic cost, spatio-temporal efficiency) are defined. MQ-decoder and arithmetic decoder can be classified in the most attractive case for dynamic reconfiguration implementation: applications without parallelism by functions. This implementation is done on an architecture designed to study dynamic reconfiguration of FPGAs: the ARDOISE architecture. The implementation obtained, based on four partial configurations of arithmetic decoder…
