Green Hills extends Integrity to multicore ARM Cortex-A9 processors

April 11, 2014 // By Graham Prophet
Green Hills Software now offers its INTEGRITY-178 tuMP real-time operating system (RTOS) for ARM-based processors. Green Hills Software partner Richland Technologies has announced an Open Standard Reconfigurable and Certifiable Computing Architecture (ORCCA) avionics computer based on an ARM multicore processor and INTEGRITY-178 tuMP.

The INTEGRITY-178 tuMP (time-variant unified multiprocessing) RTOS is intended for safety-critical and security-critical systems that are based on modern multicore processors. INTEGRITY-178 tuMP significantly improves the flexibility in how the ARM processor cores can be used. The tuMP architecture is referred to as “unified” in that a common OS controls the scheduling of all cores and the overall communications between applications. It retains all AMP and SMP scheduling capabilities while resolving their significant limitations. The introduction of tuMP for ARM-based processors follows the successful introduction in 2011 of INTEGRITY-178 tuMP for Freescale’s family of QorIQ multicore processors.

The tuMP implementation is an update to Green Hills Software’s INTEGRITY-178 single-core product; INTEGRITY-178 tuMP for ARM also supports the ARINC-653 (Part 1 supplement 3 and Part 2 supplement 2) interfaces and operating system capabilities necessary to be aligned with the Future Airborne Capability Environment (FACE™) V2.0 Technical Standard. For systems requiring compliance to RTCA/DO-178B/C, Green Hills Software provides Level A certification evidence for INTEGRITY-178 tuMP.

Richland Technologies designed and built their ARM-based ORCCA avionics computer to satisfy severe Space, Weight and Power (SWaP) requirements. Richland’s CortexTM-A9-based ORCCA platform offers dual redundant, low-power, high-performance processing and graphics capability, with flexible I/O configurations. The availability of INTEGRITY-178 tuMP for ARM allows Richland to offer seamless portability of the DO-178B/C-certifiable ORCCA software platform (device and I/O drivers, middleware and FACE 2.0 Technical Standard-aligned software applications) between QorIQ and Cortex-A9-based platforms.

INTEGRITY-178 tuMP is available for ARM Cortex-A9 processors and is supported by Green Hills Software’s MULTI/AdaMULTI integrated development environment (including optimising C, C++ and Ada compilers).
