The Ultrascale+ MPSoC includes four ARM 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.
“We continue to recognize our aerospace customers’ requirement for significant reductions in Size, Weight and Power (SWaP) using the latest 64-bit multicore technology such as that found in the Ultrascale+. However, in order to meet these SWaP objectives across the variety of multicore parts available today, an operating system must provide advanced functionality that allows users to maximize core efficiency and throughput while simultaneously meeting the software assurance requirements of RTCA/DO-178B Level A,” said Dan O'Dowd, founder and chief executive officer of Green Hills Software. “...[the] INTEGRITY-178 tuMP operating system uniquely provides the ability to integrate a multicore processor into a flight-critical system while achieving optimal use of all cores in a deterministic manner and also complying with the certification community’s CAST-32A position paper for multicore processors.”
