Semi-automatic Source Code Generation for the Hardware-Implementation of a Parallelizable and Configurable Error Correction Unit

Bose-Chaudhuri-Hocquenghem (BCH) codes are among the most used error correction codes. They are used in DVB-T receivers and are deployed for error correction in flash memories. Nowadays codes with large codeword lengths and large error correction capability are used which is a new challenge in hardware-development for the encoder and decoder. This article presents a parallel BCH error correction unit with configurable error correction capability. Furthermore, it describes how tools for source code generation can be used to support the development process.
