PrismTech

OpenFusion RTOrb Ada Edition is PrismTech’s high performance, robust and feature rich Ada ORB specifically designed for use in mission critical real-time applications. It complies with the latest revisions of the CORBA Specification and implements many advanced CORBA features such as Objects By Value (OBV) and CORBA Messaging, including Asynchronous Method Invocation (AMI).

OpenFusion RTOrb Ada Edition is particularly suitable for demanding applications in sectors including: defense, aerospace, air traffic management, telecom, data communications, satellites, railways and financial systems.

Tried and Tested Architecture

Based on international standards, the architecture of OpenFusion RTOrb Ada Edition is open and flexible. The ORB’s high performance is a direct consequence of its architecture design. OpenFusion RTOrb Ada Edition is built on a product core that has been tried and tested in demanding applications in both the military and commercial sectors. The core design and algorithms are common to all OpenFusion real-time ORBs. The architecture of OpenFusion RTOrb Ada Edition supports not just minimumCORBA, as is the case with most real-time ORBs, but a fully capable, enterprise level ORB. This is a rarity in real-time ORBs, let alone one written in Ada! It is therefore uniquely positioned to provide a single solution for different needs and uses, supporting both real-time and business applications in a single ORB.

OpenFusion RTOrb Ada Edition Benefits

• High quality proven mature core Ada ORB with a worldwide customer base in sectors including air-traffic control, C4I defense and aerospace. The ORB is native Ada with no assembler or C callouts that could make the task of proving correctness using SPARK-like tools difficult.
• Ada95 memory-safe implementation designed for and suitable for use in high availability, mission critical applications.
• Memory allocation is performed in a manner that makes access fast, highly predictable and with minimal fragmentation.
• Flexible architecture provides a pluggable transport framework enabling replacement of the default transport with other transports to meet specific requirements.
• High performance of the Ada core is exemplified by the fact that even the "Any" type imposes minimal overhead. The ORB exhibits consistently high performance across a range of data types over both TCP/IP and shared memory transports.
