Tiny application-specific programmable processor for BCH decoding

We present a novel design for a tiny application-specific programmable processor for BCH decoding. The design is optimized for use in a PUF key extractor, where low-area overhead is extremely important. Due to it's flexible nature, it can support a wide range of BCH codes. The complete design for a BCH(413, 296, 13) decoder requires only 1% (less than 70 slices) of the available resources of a small FPGA.
