Green Hills Software multicore operating system picked for DO-178B Level A Certification

Green Hills Software, a provider of high assurance operating systems, has been selected by a US supplier of guidance and navigation equipment for commercial and military aircraft to provide its DO-178B Level A-compliant real-time multicore operating system for their next generation of equipment based on the Xilinx Zynq® Ultrascale+ MPSoC, the company said.

The Ultrascale+ MPSoC includes four Cortex®-A53 64-bit cores which will run Green Hills Software´s INTEGRITY®-178 Time-Variant Unified Multi Processing (tuMP) operating system.

The DO-178B Level A-compliant operating system capabilities required by Green Hills Software´s flight-critical avionics and mission equipment customers using an ARMv8 based architecture (e.g. Ultrascale+´s quadcore Cortex-A53s) includes full 64-bit operational support for all applications, the ability to execute SMP and/or AMP applications on all four cores simultaneously, support for the latest ARINC-653 multicore partitioning requirements as defined in Part 1 Supplement 4 of the standard (including SMP operation as defined in Section 2.2.1 of Supplement 4), a safety-critical IP network stack that supports multiple IP clients at differing safety levels, and the ability to host applications that align with the Future Airborne Capability Environment (FACETM) Technical Standard.

Green Hills Software has a long history as an innovative leader in enabling critical embedded system designers to fully utilize advanced microprocessor features such as those found on today´s multicore SoCs.

Beginning with Green Hills Software´s pioneering efforts of robust partitioning for single-core processors, its list of accomplishments continues today with certified operating systems for today´s highly capable ARMv8 multicore SoCs.
