INTEGRITY is a real-time operating system (RTOS) produced and marketed by Green Hills Software. It is royalty-free, POSIX-certified, and intended for use in embedded systems needing reliability, availability, and fault tolerance. It is built atop the velOSity microkernel and is intended mainly for modern 32- or 64-bit embedded system designs that support an MMU. INTEGRITY uses hardware memory protection to isolate and protect itself and user tasks from incorrect operation caused by accidental errors or malicious tampering. Supported platforms include variants of ARM and XScale, Blackfin, Freescale ColdFire, MIPS, PowerPC, and x86 computer architectures.There is also INTEGRITY-178B, a certifiable version for Safety-Critical applications.
