4. Operating Principle
The VMIVME-7807 single-board computer operates based on PowerPC real-time parallel computing, VME64x high-speed bus scheduling, hardware fault self-recovery and permanent power-down data protection. After power-on, it completes full hardware self-check, chip initialization, bus protocol matching and system boot loading automatically to enter real-time main control state.
During operation, the PowerPC processor executes control logic, data acquisition and multi-device scheduling tasks in parallel. The VME64x bus builds a high-speed data link, and the 4-level arbitration mechanism allocates bus resources reasonably, realizing efficient data synchronization and instruction interaction with rack-mounted I/O and expansion modules with low delay and high precision.
The on-board fault tolerance system monitors system status in real time. The hardware watchdog triggers automatic recovery from system deadlock and exceptions, and non-volatile storage retains key data and fault logs to avoid system paralysis. The rugged wide-temperature structure and full-link diagnosis mechanism ensure long-term stable and high-precision operation of VME embedded control systems under complex industrial conditions.
