	OCEOSmp is a real-time pre-emptive fixed priority operating system that can be used in applications that require European Cooperation for Space Standardization Category B or ISO 26262 standards. It has a small memory footprint (<20 kBytes), requires only one system stack per CPU rather than a stack for each task, and provides support for precisely timed data outputs independent of task scheduling. OCEOS supports applications running on RISC-V, ARM, & SPARC based hardware.		OCEOSmp is a multicore real-time pre-emptive fixed priority operating system that can be used in applications that require European Cooperation for Space Standardization Category B or ISO 26262 standards. It has a small memory footprint (<20 kBytes), requires only one system stack per CPU rather than a stack for each task, and provides support for precisely timed data outputs independent of task scheduling. OCEOS supports applications running on RISC-V, ARM, & SPARC based hardware.

	OCEOSmp is designed to be suitable for high reliability embedded systems. It is not started initially on power up but is started by the main application code, to which it may return if a fatal error is detected. It is designed to be transparent with information stored at statically allocated locations and accessible both while OCEOSmp is running and after it exits.
