Abstract
An error correcting system uses an error location polynomial which is defined by double correction BCH codes each consisting of the elements of a Galois field GF(2.sup.m), and thereby generates error locations .sigma..sub.1 and .alpha..sup.2 and error patterns e.sub.1 and 2.sub.2. The system has a first data processing system for performing only addition and multiplication to generate the error locations .sigma..sub.1 and .alpha..sup.2, and a second data processing system for performing only addition and multiplication to generate the error patterns e.sub.1 and 2.sub.2. The first data processing system comprises a syndrome generator, a memory, an arithmetic logic unit, registers, latch circuits, registers, adder circuits and a zero detector. The second data processing system comprises a gate circuit, latch circuits, an arithmetic logic unit, and the registers of a memory.
