Configurable Open System Architecture (COSA) - North Atlantic Industries


Accelerate Your Time-to-Mission™ with COSA®

Our massively Configurable Open Systems Architecture™ (COSA®) gives you the most modular, agile and rugged COTS portfolio of embedded smart modules, I/O boards, Single Board Computers, Power Supplies and Ruggedized Systems of its kind. All are pre-engineered to work together today and be easily changed, reused or re-purposed down the road. We’ve used FPGAs and SoCs to create smart modules that enable you to rapidly create configurable mission systems – while reducing or eliminating SBC overhead.

COSA meets a wide range of complex and time-critical requirements in a distributed, intelligent, software-driven architecture that allows you to rethink the way you engineer power-critical and I/O-intensive mission systems.


Distributed I/O with Single API Programmability


Optimized SWaP

COSA Design Advantages (2:56)

Here's How it Works:

  1. Select I/O Boards, Single Board Computers, Power Supplies or Rugged Systems to meet your requirements.
  2. Customize it in modular fashion - select from more than 70 available, high-density, fully tested I/O, Communications, Measurement & Simulation smart function modules.
  3. Leverage our free software libraries, our source-code and comprehensive API to jump-start development & speed your time to test.
  4. Easily adjust board configuration to add or swap functional capabilities if requirements change.

COSA Modules, Boards and Systems

Over 70 high-density, COSA smart modules are available for placement on our intelligent I/O Boards, which can operate as standalone systems. The breadth of available, off-the-shelf functions makes it likely that we can meet your I/O requirements, no matter how intense or precise, better than any other COTS systems supplier and without NRE.

Further, our OpenVPX, VME, cPCI and PCIe boards can be placed into Rugged COSA Systems that range from a single module to high-density systems supporting up to 10 motherboards and 60 smart modules (and virtually everything between).

COSA Software & Processing Advantages

Dedicated FPGAs embedded on our smart modules provide unique software and processing advantages that drive time and cost out of our customer’s design, development and qualification schedules. The programmability, intelligence and self-monitoring capabilities put more I/O capability into the modules themselves so you can reduce the processing load on the SBC and deliver more capabilities at the edges of your applications.

NAI’s COSA Architecture is helping some of the world’s largest Military, Commercial Aerospace and Industrial companies meet complex requirements with high-density, COTS-based solutions in less space, with lower power requirements, no NRE and faster timelines than is possible with alternative solutions.
