ASELSAN’s launch customer for its new advanced Multifunctional Display and Mission Computer product line is the Turkish Utility Helicopter Program (TUHP), which features the T-70 Helicopter, a derivative of Sikorsky Aircraft’s S-70i Black Hawk helicopter. The Multifunctional Display and Mission Computer contains up to four Freescale P2041 multicore processor modules, all running the INTEGRITY-178 tuMP multicore operating system, and is intended to support glass cockpits, multifunction displays, flight management systems, and moving map systems.
“After performing an extensive research and selection process for a safety-critical multicore RTOS able to meet both our functional and assurance requirements for the Multifunctional Display and Mission Computer product line, we came to the conclusion that INTEGRITY-178 tuMP is the most advanced and mature solution available with its DO-178B Level A certifiable features and deterministic operation,” said Yüksel Serdar, Head of Avionics Business Line at ASELSAN. “INTEGRITY-178 tuMP provides our system designers the ability to safely combine AMP and SMP operation according to precise core and time partition assignments, yielding the deterministic and highly efficient throughput that we required from our multicore Multifunctional Display and Mission Computer product line.”
“Green Hills Software is proud to be part of ASELSAN’s newest avionics product line incorporating Freescale’s industry-leading multicore technology,” said Dan O’Dowd, founder and chief executive officer of Green Hills Software. “As a supplier to ASELSAN since 2008 with our DO-178B Level A certified INTEGRITY-178 RTOS, we appreciate the opportunity to continue supporting their new Multifunctional Display and Mission Computer product line with our industry-leading INTEGRITY-178 tuMP operating system. With their reputation as a proven avionics supplier, we anticipate ASELSAN to establish a worldwide leadership position with their new multicore-based family of avionics equipment.”
The Green Hills Software INTEGRITY-178 tuMP multicore operating system has been shipping to Green Hills aerospace and defence customers since 2010. It builds upon a proven fourteen-year service history and certification pedigree by incorporating multicore operating system capabilities, including support for AMP and SMP. INTEGRITY-178 tuMP defines groupings (called affinity groups) of how cores will be utilised by one or more applications, with the grouping of cores and applications being permitted to vary over time. Sets of affinity groups are then scheduled independently of other sets of affinity groups, permitting time-lines that closely correspond to application requirements, yet also permitting other sets of affinity groups to be developed that can make use of time windows where cores are not being utilized. Support for multiple simultaneous schedules further extends the tuMP scheduling capabilities, permitting tailoring of available applications and processor time resources based on the vehicles’ operational needs, such as flight or combat phase.
INTEGRITY-178 tuMP extends partitioning support beyond single-core processors, ensuring that this highly flexible capability can continue to be effectively used to host multiple applications while preserving resources for application growth without concern about future availability of new single-core processor designs. INTEGRITY-178 tuMP offers complete support for the ARINC-653 Part 1 standard as well as Part 2 optional features such as Sampling Port Data Structures, Sampling Port Extensions, Memory Blocks, Multiple Module Schedules and File System. INTEGRITY-178 tuMP also aligns with the FACE 2.1 Safety Base and Security profiles.
