SYNCHRONIZER CIRCUIT

摘要

This invention is related to an integrated circuit for the synchronous operation of two identical digital boards comprising microprocessors, wherein it allows each board to access to each other's memories (5), produces the necessary signals to start the synchronised operation of boards, allows the microprocessors (1) on both boards to have a synchronised operation on a command interpretation basis to provide synchronised operation, determines the probable incompatibilities by comparing the address and data buses (7, 8) of both microprocessors (1) during the synchronised operation, reports the incompatibility to both microprocessors (1) by a break signal, and allows the microprocessors (1) to read the address and data bus (7, 8) values of an incompatibility by writing the said values on an internal log.
