Abstract
General operating system services in Duplex Multiple Environment Real Time (DMERT) are provided by a kernel and a set of cooperating processes. These services support a multitude of process-oriented features that include a rich set of interprocess communication mechanisms and a sophisticated collection of memory manipulation primitives. The operating system provides processes with two scheduling alternatives and various creation and termination options. The cooperating processes include input/output drivers and device handlers that enable processes to communicate with a variety of peripheral devices. Another set of processes simulates a UNIX™ operating system and file system.
