We are delighted to announce that our paper „Lower Bound-oriented Parameter Calculation for AN coding“ written by Juliana Hildebrandt, Till Kolditz, Dirk Habich, and Wolfgang Lehner has been accepted at the International Symposium on Information Theory and Its Applications (ISITA). ISITA is the leading conference on information theory.

Abstract: The hardware as well as software communities have recently experienced a shift towards mitigating bit flips issues in software, rather than completely mitigating only in hardware. For this software error mitigation, arithmetic error coding schemes like AN coding are increasingly applied because arithmetic operations can be directly executed without decoding and bit flip detection is provided in an end-to-end fashion. In this case, the encoded data words are computed by multiplying a constant integer value A onto each original data word. To reliably detect b bit flips in each code word, the value A has to be well-chosen, so that a minimum Hamming distance of b+1 can be guaranteed. However, the value A depends on the data word length as well as on the desired minimum Hamming distance. Up to now, a very expensive brute force approach for computation of the value for A is applied. To tackle that in a more efficient way, we present a lower bound-oriented approach for this calculation in this paper.
