A network operating system (NOS) to support real-time distributed Ada applications

An NOS implemented on Texas Instrument's Mission Computer is described. The NOS is targeted to advanced common module architecture, and supports distributed Ada applications by implementing an intermodule messaging scheme. In addition, the NOS contains provisions which support the concept of run-time reconfiguration in order to more easily allow full use of available hardware resources in the event of mission mode changes or degraded mode operation. The NOS has evolved from a VHSIC Phase I IBUS implementation to the VHSIC Phase II PI-Bus target implementation. Improvements were made in this evolution due to redesign based on the first implementation and due to superior PI-Bus hardware support.<
