This year's design task is the BCH (Bose, Chaudri, Hocquenguem) Digital Error Correction Circuit, which is based on Grois Field Mathematics. Since this contest is mainly for University students, the code size in the task is relatively small to let student to design easily. In addition, some task level is prepared for several students levels.

The requirements of the design is to write HDL (VHDL or Verilog HDL) and to synthesize digital circuits using Synopsys design analyzer or any other EDA tools. Making FPGA is also optional but our judges love to see your FPGA designs.

Figure 1 shows the encoding and decoding system diagram. There are two big blocks such as BCH encoder and BCH decoder. This year’s design task is the DECODER. In order to send ASCII data, the information width is 7 bits. By adding 8 bit parity bits, the code length is 15 bits. Then, we call BCH(15,7) system. The BCH(15,7) can correct 2 bit errors in 15 bits code.

DECODER receives 15 bit packet with error bits included and performs Error Correction operation. Since BCH is much simpler than Reed-Solomon (RS) code, it is very good for students’ design contest task. Actually, the BCH decoder can be realized by Grois field remainder circuit and Table circuit.
