Abstract
To carry out the processing operations relating to the implementation of a Viterbi algorithm, an integrated circuit comprising a processor and a coprocessor is made. The coprocessor is constructed so as to carry out operations of accumulation, comparison and selection in order to limit or reduce the work of a processor that would have to carry out these operations. By judiciously choosing the structure of the coprocessor, it is possible to make this co-processor sufficiently programmable so that it is suited to various situations of implementation of the Viterbi algorithm.
