Development of a CTRON-conformant operating system on the OKITRON-SV processor system

The OKITRON series of products are microcomputer systems running a CTRON-specification operating system (OS). The latest of the series to be developed is the mid-range OKITRON-SV single-board computer system, which is reported on. OKITRON-SV is equipped with a CTRON-conformant Basic OS and Extended OS, and is intended for use as a highly functional real-time platform for communication systems. It adopts the MC68030 microprocessor in a hot-standby duplex processor configuration, and features a virtual memory system, making use of the built-in MMU (memory management unit) in the MC68030. The authors outline the hardware configuration of the system, and discuss technical issues involved in their implementation of the CTRON specifications. They further describe the system features, and the environment supporting development of application software to run on the OS.<
