Abstract

This paper presents a hybrid multimode Bose Chaudhuri Hocquenghem (BCH) encoder for reducing the input length of Syndrome calculation (SC) based on re-encoding approach. In previous re-encoding approaches, a conventional BCH encoder with long generator polynomials is used as a remainder operator to reduce the input length of SC. However, the input length is still large since long polynomial is used as a denominator of remainder operator for re-encoding. In the proposed approach, several minimal polynomials are employed as the denominators of remainder operators by utilizing the hardware of hybrid multimode BCH encoder. As a result, the minimum input length for SC can be employed for SC implementation through reencoding scheme, which leads to considerable area and latency reduction in SC module design. The proposed BCH encoder architecture and reduced SC modules are implemented using Samsung 65nm technology. The experimental results show that, in case of BCH (8640, 8192, 32) codes, the total area of SC modules are reduced by 96% compared to the previous re-encoding based SC module design, while the proposed multimode BCH encoder architecture also provides the reconfigurable error correction capability for 1 ≤ tsel ≤ 32.
