DIVIDER DEVICE TO DIVIDE A FIRST POLYNOMIAL BY A SECOND ONE

The divider device is used in a digital communication network to detect bit errors by dividing a first polynomial corresponding to a first bit sequence by a second polynomial, called a generator polynomial, represented by a second bit sequence. The device performs, by means of an iterative process, an n-bit parallel division of the first bit sequence by the second one, i.e. n bits at a time. It includes an addition circuit A to n first inputs 17/IO of which the n bits are applied and a divider circuit D to n inputs of which n respective outputs of A are coupled back via a register circuit R and n outputs of which are coupled to n second inputs of A. The remainder of the division is generated at n outputs of R.
