Product Performance

The processor’s single-cycle instruction execution time is ≤2ns, supporting real-time operating systems (VxWorks, QNX) with task scheduling delay ≤1ms, meeting industrial-grade real-time control requirements. The VME64x bus interface supports 32-bit/64-bit data transmission with a maximum rate of 160MB/s, and the bus arbitration response time is ≤500ns during multi-master device concurrent access, avoiding bus congestion.

The Ethernet port has a data transmission delay of ≤10ms, supporting industrial-grade real-time communication protocols (e.g., Modbus TCP) to realize real-time data interaction with upper monitoring systems. Built-in hardware-level fault diagnosis circuit can monitor the status of key components such as processor, memory, bus interface and power supply, with diagnostic coverage ≥98%, and fault information is uploaded to monitoring nodes in real time via serial port or Ethernet.

The module has passed VMEbus Consortium compatibility testing, and can be seamlessly compatible with VME I/O modules and communication modules from different manufacturers, supporting hot swapping (requires rack support) with no shutdown required during replacement. Industrial-grade wide-temperature design and anti-EMC capability ensure stable operation in complex industrial environments, with Mean Time Between Failures (MTBF) ≥600,000 hours (MIL-HDBK-217F, 25℃ environment).
