In this paper, the first flexible architecture dedicated to block turbo decoders is presented. The major innovation concerns the component code that is used by the block turbo code. In fact, our architecture is able to decode BCH and Reed-Solomon codes with single or double correction power. To the authors? knowledge, this is the first architecture implementing Reed-Solomon block turbo codes. This approach makes it possible to select the block turbo decoder architecture using optimum component codes in any circumstance. Our flexible elementary SISO decoder is dedicated to extended binary BCH codes (32,26) and (32,21) and to non-extended Reed-Solomon codes (31,29) and (31,27). Experimentation has been done on a Stratix-based NIOS development board.
