Abstract
A circuit for generating an N-bit cyclic redundancy code of a k-bit digit d, the code based on a reconfigurable generator polynomial P of degree N, the circuit including a dynamic table comprising a multiplication sub-table storing products resulting from multiplication by the polynomial P of each element definable over k bits, in the order of the scalar values of the k-bit elements; a division sub-table storing quotients resulting from Euclidean division by the polynomial P of each k-bit element shifted by N bits to the left, in the order of the scalar values of the k-bit elements; and a group of first multiplexers, each multiplexer connected to be indexed by a respective cell of the division table to transmit the contents of a corresponding cell of the multiplication table to an output of the dynamic table, of same rank as the respective cell of the division table.
