DDC-I Announces In-Flight, Multicore, exFAT File System for Deos Safety-Critical DO-178C Avionics RTOS

Reusable DAL-A-verified file system ideal for avionics systems requiring high data storage capacity, low-latency real-time performance and in-flight random read-write access file system

Phoenix, AZ , February 28, 2023. DDC-I, a leading supplier of safety-critical operating systems and tools, today announced an in-flight capable file system for safety-critical avionics applications requiring high-performance random read/write access. Utilizing the popular exFAT file system for data portability on and off the Avionics device, the Deos™ Volume Management System (DVMS) supports single-core and multicore SafeMC™ operation. Additionally, DVMS offers flexible APIs including ARINC-653 Part 2 and POSIX style interfaces, and it is verified to DO-178C Design Assurance Level A (DAL A). The low-latency, XML-configurable file system also features a Media Abstraction Layer (MAL) that decouples media device specifics, supports mixed DAL application access with support for DMA at DAL A, maintains time partitioning, and is available with both power-fail-safe journaling and lossless compression.

“DVMS and the exFAT file system, with DO-178C verification evidence to DAL A, provides effortless mobility for in-flight safety critical data on/off the avionics platform to Windows and Linux based workstations,” said Greg Rose, vice president of marketing and product management at DDC-I. “The Deos RTOS with its SafeMC technology, DVMS with exFAT, and our comprehensive OpenArbor development tools provide a turnkey avionics software development and deployment solution for systems that require high performance multicore operation and data portability.”

DVMS, adaptable through XML configuration files, was developed as a user space DO-178C DAL-A shared library that allows file operations within the time and space partition of the calling application. The DVMS utilizes the exFAT format, a standard file system format for high-capacity memory devices, that enables data to be easily transferred on or off Deos systems through removable media to Linux, Windows and other workstations.

DVMS supports single core, multicore, and multiple concurrent partition access to the file system (re-entrant operation). Each user partition can own one or more DVMS partitions. The DVMS execution time is assigned to the calling application. Each DVMS partition, or volume, may contain one or more files, with DVMS handling mutual exclusion for access to the volumes. The DVMS libraries utilize a Media Abstraction Layer (MAL) that makes it hardware media agnostic. The MALs are available for RAM Disk, a RAW interface, NAND/NOR flash, SATA, and CompactFlash and/or can be modified for customer specific storage media. DMVS is available for Arm, PowerPC and X86 processors.

DVMS features an optional journaling library in which file system data structures (metadata) as well as the file data itself are written to a temporary, but power-cycle-preserved area before committing them to their proper location in the storage device. DVMS also features an optional compression library, a port of the popular zlib lossless data compression library that enables compression/decompression of files on a per volume basis.

DDC-I Presents Paper at Safety-Critical Systems Symposium 2022

February 7, 2022. Bristol, UK. DDC-I, a leading supplier of software and professional services for mission- and safety-critical applications, today announced that it will present a paper on multicore design considerations and optimization for safety-critical avionics at the Safety-Critical Systems Symposium (SSS’22). The 30^th anniversary Symposium will be held in Bristol, UK from February 8-10 at the Bristol Royal Marriott Hotel and blended online as a live-streamed event through the SCSC website and the Whova application.

The Safety-Critical Systems Symposium comprises three days of live presented papers, including keynote presentations and submitted papers, with a 30-year retrospective and 30-year look ahead. There will also be an evening session on the Wednesday with additional talks. The Symposium is for all of those in the field of systems safety, including engineers, managers, consultants, students, researchers and regulators. It offers wide-ranging coverage of current safety topics with a focus on industrial experience, includes recent developments in the field and progress reports from the SCSC Working Groups, and covers all safety-related sectors including aerospace, defense, health, highways, marine, nuclear and rail.

“We are excited to be part of the 30^th anniversary of the Safety-Critical Systems Symposium and look forward to bringing avionics designers up to speed on the latest developments in multicore technology,” said Greg Rose, vice president of marketing and product management at DDC-I. “Our presentation is a must see for avionics developers who want to utilize the latest multicore technology while meeting the worst-case execution requirements defined in the FAA’s CAST-32A position paper for Multi-core Processors. Our Deos SafeMC technology uniquely resolves the CAST-32A multicore objectives, enabling developers to achieve unmatched performance and determinism for safety-critical applications.”

Creating a multi-core platform for safety-critical avionics is the next major step for most avionics manufacturers. While multi-core processors are commonly used in most other markets, the avionics industry has taken years to trust multi-core technologies. Acceptance has been slow due to an avionics system’s stringent safety and deterministic requirements. As a result, years of study have been invested by certification authorities and industry suppliers to identify the issues multi-core processors pose for safety-critical systems. Formalized positions of these efforts are the FAA CAST-32A Positioning Paper, and EASA’s multi-core Certification Review Item (CRI). The crux of these papers (regarding software) focuses on bounding and controlling the interference patterns that exists when processor cores share resources.

This paper, scheduled for Thursday February 10 at 13:05, highlights the challenges of implementing multi-core processors for avionics developers. It will present Deos SafeMC and show how it helps address CAST-32A objectives by utilizing unique operating system features designed for minimizing and bounding contention issues within multi-core environments. Features such as cache partitioning, memory pooling and safe scheduling enable users to configure the memory architecture to minimize cache thrashing and schedule applications across all cores. Together, these capabilities enable developers to employ modern systems that orchestrate software applications such that conflicts over shared resources are minimized and the overall performance advantages of multicore processors can best be utilized.

Deos real-time operating system provides deterministic, low-jitter, high-performance, DO-178C multi-core platform for 11th Generation Intel® Core™ Processors

Phoenix, AZ – September 21, 2021 – DDC-I, a leading supplier of software and professional services for mission- and safety-critical applications, today announced that it has teamed with Intel to port its Deos™ DO-178C safety-critical real-time operating system and Eclipse-based development tools to Intel’s 11th Generation Intel® Core™ i7 multi-core application processor. Intel Core i7 processors running Deos provide an excellent platform for a wide number of applications, including displays and high compute smart sensors.

Deos has supported the x86 processor architecture with DAL-A artifacts since 1998, with thousands of x86-based Deos systems certified and flying today. With Intel Core i7 processors, Deos extends its existing support for the Intel Atom®, Intel® Xeon®, and other i7 architectures, providing a common certification package (at the binary level) and development tools across all these processors, including our DO-330 qualified tools.

The Intel Core i7 SoC application processor is the 11th generation of Intel® Core™ architecture. Combining 4 CPU cores operating at up to 4.4 GHz with an Intel® Iris® X^e graphics processor and up to 12 Mbytes of cache, Intel Core i7 features Enhanced Media (AV1 Codec/12b support via 2 VDBOX) and AI/DL Instruction Sets with VNNI support for CV/AI and OpenVINO. Intel Core i7 also provides four DP/HDMI outputs (four 4K or two 8K resolution display outputs), 4 PCIe Gen4 Lanes (CPU), and 12 HSIO (PCH) channels with support for 802.11ac, PCIe Gen 3, and USB4.

“Intel Core i7’s high-performance multi-core architecture, on-chip graphics, and AI processing, together with the availability of certification data, makes it very attractive to our avionics customers,” said Greg Rose, vice president of marketing and product management at DDC-I. “Our SafeMC™ multi-core technology leverages many of these capabilities, employing techniques like cache partitioning, memory pools, time-space partitioning and slack scheduling. Together they provide an efficient, robust, and deterministic platform that builds on Intel’s technology to maximize performance while providing a certifiable multi-core environment by reducing multi-core interference and worst-case response.”

“Intel Core i7 offers a high degree of functional integration, making it ideal for e-Cockpit advanced displays and high-compute smart sensors,” added Tony Franklin, General Manager of Federal and Aerospace group at Intel. “DDC-I has been a long-time supporter of the x86 architecture, and we are pleased to be working with them again to offer our joint avionics customers a world-class multi-core safety-critical RTOS platform for our 11th Generation Intel® Core™ i7 processors.”

Deos is a safety-critical embedded RTOS that employs patented cache partitioning, memory pools, and safe scheduling to deliver a certifiable system with higher CPU utilization than any other certifiable safety-critical COTS RTOS on multi-core processors. First certified to DO-178 DAL A in 1998, Deos provides a FACE™ Conformant Safety Base Profile that features hard real-time response, time and space partitioning, and both ARINC-653 and POSIX interfaces.

Deos runs on a broad range of processors. With an emphasis on multi-core applications, Deos scales well in the gamut of avionics applications, from highly deterministic deeply embedded FADECs (Full Authority Digital Engine Control) and flight controls to complex high throughput displays and mission computers.

SafeMC technology extends Deos’ advanced capabilities to multiple cores, enabling developers of safety-critical systems to achieve best in class multi-core performance without compromising safety-critical task response and guaranteed execution time. SafeMC employs a bound multiprocessing (BMP) extension of the symmetric multiprocessing architecture (SMP), safe scheduling, and cache partitioning to minimize cross-core contention and interference patterns that affect the performance, safety criticality and certifiability of multi-core systems. These features enable avionics systems developers to address issues that could impact the safety, performance and integrity of a software airborne system executing on Multi-Core Processors (MCP), as specified by the Certification Authorities Software Team (CAST) in its Position Paper CAST-32A for Multi-core Processors.
