发明名称 ERROR CORRECTING SYSTEM
摘要 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(2m), and thereby generates error locations sigma 1 and alpha 2 and error patterns e1 and 22. The system has a first data processing system for performing only addition and multiplication to generate the error locations sigma 1 and alpha 2, and a second data processing system for performing only addition and multiplication to generate the error patterns e1 and 22. 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.
