DDC-I pairs Deos RTOS with TSN networking on AMD edge platform

DDC-I has launched a MOSA-aligned edge platform that combines its Deos safety-critical RTOS with TTTECH’s 10G TSN IP on AMD Zynq UltraScale+ hardware. The goal is to replace federated sensor-node architectures with a smaller, more deterministic endpoint for avionics, land and marine systems.

Why it matters: - The new platform aims to push deterministic networking and safety-critical compute closer to the edge. - DDC-I is positioning the system as a SWaP-optimized alternative to federated sensor-node architectures. - The combined design is intended to cut wiring weight, harness complexity and reliance on intermediate data interface units. - The platform targets avionics, land and marine applications that need modular, certifiable edge nodes.

What happened: - DDC-I announced a new MOSA-aligned system-on-chip platform for edge processing applications. - The platform is based on the AMD Zynq UltraScale+ SoC. - The design combines the Deos DAL A, FACE-conformant, DO-178C safety-critical RTOS with TTTECH’s TSN-End Point IP Integration Kit. - The system extends TSN backbone networks to the edge. - DDC-I described the result as an endpoint control and sensor node, a Data Concentrator Unit, or an intelligent TSN interface solution.

The details: - TTTECH’s networking IP supports 1 Gigabit and 10 Gigabit TSN and complies with the IEEE 802.1DP TSN aerospace profile. - The platform is meant to support common, reliable, real-time and low-latency data delivery across multiple platform providers. - DDC-I says the edge design helps developers build modular nodes with higher performance and greater functional density. - The architecture is intended to make certification and maintenance easier as new capabilities are added. - In avionics use cases, moving control and high-speed networking closer to the edge reduces wiring weight and harness complexity. - TSN’s higher bandwidth supports more devices per line. - DDC-I says scaling TSN to smaller devices lowers size, weight, cost and power consumption. - Deos scales from single-core applications to multi-core systems. - Developers can start with a single-core Deos setup and move to multi-core without a redesign. - Deos includes built-in multi-core synchronization for distributed control and redundant systems. - Deos uses modular software components that can be reused from one certifiable project to the next, down to the binary level. - DDC-I says that reuse approach supports a high-integrity RTOS proven through prior FAA and EASA processes. - The reuse model is also designed to help customers move to newer processor families without recompiling. - If the four Arm A53 cores in UltraScale+ become limiting, applications and other system executables can move to AMD’s Versal 2 family with eight Arm A78AE primary cores. - Where space allows, developers can also move to a MOSA-aligned card-level solution from companies such as North Atlantic Industries. - DDC-I said the platform can use Ultrascale+ security features for secure boot, encryption, secure communications and system updates. - Datagram Transport Layer Security can be added through the Deos TLS module if a secure TSN network is required. - TTTECH’s Ultrascale+ TSN development reference platform includes Deos, DDC-I’s Open Arbor development tools and a TSN driver. - The turnkey setup is designed to help customers start building a TSN endpoint controller or sensor node for safety-critical use cases.

Between the lines: - DDC-I is tying together three market trends: safety-critical software, deterministic Ethernet and edge compute. - The pitch is not just performance. It is also certification reuse, easier maintenance and lower integration cost. - The ability to reuse binary-level OS modules across projects is a key differentiator for programs that face long certification cycles. - The migration path to newer processors suggests DDC-I is trying to reduce platform lock-in for long-lived defense and aerospace programs.

What's next: - DDC-I is offering the platform as a starting point for customers building safety-critical TSN edge nodes. - The company expects the approach to support next-generation aerospace and defense systems as TSN adoption grows. - Developers can extend the same architecture across different endpoint, control and sensor-node deployments as system needs change.

The bottom line: - DDC-I is bundling certified RTOS software and deterministic TSN networking into one edge platform to simplify safety-critical aerospace and defense deployments.
