Dolmen
The Future Airburne Capability Environment (FACE) provides a well-defined environment for developing portable applications. Dolmen is aligned with the FACE Technical Standard 2.0 and provides the I/O Services and Transport Connections upon which any FACE-conformant application can run.
Complete
Dolmen provides the I/O Services and Transport Services Segments to provide a complete FACE environment. From controlling discretes and the MIL-STD-1553 bus to POSIX Sockets and Message Queues, Dolmen is the complete FACE solution.
Reliable
Dolmen is engineered for the most resource-constrained environments, including low-power processors and limited-memory environments. Dolmen was designed according to MISRA guidelines and DO-178B considerations.
Precise
Dolmen faithfully implements all requirements from the FACE Technical Standard Edition 2.0. Every requirement is traceable in Dolmen and automated testing achieves nearly 100% statement level coverage.

Generate Code
The Dolmen development tools include an IDL compiler that takes industry-standard CORBA IDL and produces the FACE-specific C++ transport code automatically.
Quoit
FACE provides an excellent framework for developing portable applications, but the official API can be cumbersome. Quoit is a C++ framework that hides much of the complexity of FACE and allows you to develop applications quickly while still maintaining FACE-conformance.
Simple
Quoit provides a number of classes that abstract the I/O and transport services data formats so you can focus on the meaning, not the layout. Quoit sits between you and the FACE environment, such as Dolmen, and manages I/O services and transport connections automatically.
Future-proof
FACE is a living standard and is moving faster than most developers can keep up with. Let Quoit handle the changes between FACE revisions and keep your applications protected from the ever-changing standard.
Portable
Quoit not only works with Dolmen, but it will work with any FACE-conformant environment. Quoit helps maintain platform-independence by relying on the FACE environment for configuration and all data interactions.
