Green Hills Software has two royalty-free RTOS products. The POSIX conformant INTEGRITY® RTOS is memory-protected and securely partitioned for use in embedded systems that require the utmost in reliability and security. The velOSity™ microkernel, the foundation of INTEGRITY, is small and fast, making it a perfect fit for cost-sensitive, high-volume, and resource-constrained embedded applications.

INTEGRITY and velOSity employ common application programming interfaces, device drivers, BSPs, middleware and network stack support, along with a common MULTI® tools integration and debug features. Software developed for the velOSity microkernel is 100% upwards compatible with the INTEGRITY RTOS. In applications that may require virtual memory support, velOSity can be upgraded to INTEGRITY with minimal to no code changes. Should the system design call for partitioned application and device drivers, the existing design can be easily reconfigured to enable applications and device drivers to exist in their own protected virtual address partition.

•Full memory protection for tasks, the operating system, and device drivers

•Secure partitioning with guaranteed memory and processor bandwidth

•Low interrupt latency and fast, deterministic task switching

•Fully integrated with Green Hills Software’s optimizing compilers and MULTI IDE

•Support for ARM-based AT91 processors
