AutoCore.DDS — DDS/SOA Communication Middleware Family

One standard protocol (OMG DDS/RTPS), three deployment forms, covering data distribution and service-oriented communication across SOC/MPU and MCU nodes — one service-oriented language for the whole vehicle, without protocol gateways.

What is AutoCore.DDS

AutoCore.DDS is a DDS/SOA middleware family covering SOC/MPU and MCU nodes. Built on OMG DDS (DCPS) + RTPS, it provides publish/subscribe data distribution and an SOA service framework (Method / Event / Field). Three deployment forms — AutoCoreDDS (full-featured on SOC/MPU), SmartDDS (standard on MCU) and SmartDDS-lite (ultra-light on MCU) — share one wire protocol, auto-discover within the same domain and interoperate directly.

Core Strengths

One wire protocol · Three forms · Full toolchain

Unified Communication Across Domains

SOC (AutoCoreDDS) and MCU (SmartDDS / SmartDDS-lite) share the standard RTPS wire protocol: auto-discovery and direct interoperability within one communication domain, with no protocol-conversion gateway between heterogeneous nodes.

Three Forms, Fit Per Node

Full-featured (SOC), balanced (standard MCU) and ultra-light (MCU lite) forms are selected node by node according to resources, and can be mixed within the same family.

Zero Dynamic Allocation at Runtime

SmartDDS-lite generates service resources at compile time: zero dynamic memory allocation at runtime, no memory fragmentation, build-time memory budget auditing for deterministic MCU memory use.

Full SOA Support

Full coverage of Method / Event / Field service models; service definitions drive automatic Server / Client code generation — C++ on SOC and C99 on MCU from a single definition.

ROS 2 Interoperability

AutoCoreDDS runs as a ROS 2 middleware (RMW); MCU forms interoperate over standard RTPS, letting robotics and autonomous-driving algorithm assets connect directly.

Security & Toolchain

Built-in OMG DDS Security (authentication, topic-level encryption, domain / topic / endpoint access control); IDL compilation, code generation, performance testing, online debugging and SOA peer simulation.
