  描述 

  The A602 is a 6U 64-bit VME COTS computer with onboard functional safety that realizes triple redundancy on a single board to achieve fail-operational, fault-tolerant behavior. The board can also act as a fail-silent subsystem, i.e. it can shut down in case of a fatal fault. Its complex FPGA-based design helps dramatically lower software development costs as it automatically manages the system s triple-redundant processors and memory. The result: The system s redundant architecture is fully taken advantage of by software designed for a standard single-CPU board.
