The Leading Small-Footprint Communications Middleware
High-performance, ultra-low latency, publish-subscribe data distribution designed explicitly for resource-constrained, real-time, and mission-critical architectures.
Standards Compliant Data Distribution Service
Engineered for Performance
Publish-Subscribe
The Publish-Subscribe architecture supports flexible development and deployment network scenarios.
Blazing Speed
Sub-20 microsecond latency (inter-process, on-platform) and greater than 900 Mbps throughput without sacrificing quality-of-service scaling.
Comprehensive Security
CoreDX DDS Secure provides fully integrated plug-in infrastructure for secure identification, authentication, confidentiality, and access control.
Ultra-Small Footprint
Minimal line count (<50K SLOC) with a core static library under 500KB. Perfect for bare-metal, FPGA, and deeply embedded components.
Broad Platform Support
CoreDX DDS supports a wide variety of operating environments, from desktops (Linux and Windows) to deeply embedded RTOS's like FreeRTOS and INTEGRITY.
Configurability
CoreDX DDS provides the standard DDS Quality-of-Service policies coupled with extensive controls to adapt to diverse network environments and performance requirements.
Technical Specifications
A native, 100% US-developed code implementation built with zero third-party dependencies.
CoreDX DDS is composed of a foundational core written in C for high performance and low resource utilization. It includes an IDL compiler, multiple language bindings, and many additional features to satisfy a wide range of system requirements.
Written for portability, CoreDX DDS has been ported to hundreds of operating environments.
Based on Open Standards, CoreDX DDS offers code portability and network interoperability -- avoiding vendor lock-in. We are committed to ensuring interoperability with other DDS vendor implementations. This is no small task, as the standards and implementations are all evolving at different rates and with different priorities. However, Twin Oaks Computing sees interoperability as a cornerstone of the DDS value proposition.
Our software engineering processes include static and dynamic analysis targeting style, bugs, resources, and performance. We don't use AI for code development -- crtical infrastructure deserves better.

Website Rework
Please excuse our brevity while we re-work this WWW site.
The recent PHP and other vulnerabilities have us re-evaluating the Internet facing technologies that we deploy. We hope to roll out a fully functional and useful site very soon.
In the meantime, please do not hesitate to contact us directly via email or phone!
