A circuit for the (7,4) Hamming encoder is implemented based on the suggested structure with optimization of 50.5% by cell count and 75% by area. The overall Hamming code circuit architecture has been ...

The Hamming (7,4) code transforms a 4-bit data message into a 7-bit codeword by adding 3 parity bits. The 7 bits are indexed as (1, 2, 3, 4, 5, 6, 7) (1-based indexing).

By using the techniques suggested in this article, one can efficiently implement a Hamming (2072, 2048) coder on a Blackfin processor for single-bit error-correction applications at less than 0.5 ...
