Abstract :
The authors outline the implementation methods of duplicated system control functions of HC68K, a basic operating system (OS) conforming to the CTRON interface specifications. Hitachi has been confirming the multiplex and realtime processing capability of HC68K for application to their ATM switching system. In development of a small-capacity ATM node they have improved reliability of HC68K with the creation of a duplicated system control function. This function improves modeling and portability of system control functions, such as an equipment management function by complying with the IROS specifications (CTRON specification base) of Nippon Telegraph and Telephone Corporation (NTT). It was confirmed that this system satisfies the function and performance objectives and demonstrates the effectiveness of the IROS (interface for real-time operating systems) specifications
