DULUTH, Ga., 3 August 2007. Concurrent, a provider of time-critical Linux operating systems and integrated software and computer solutions for mission-critical applications, announced that Naval Surface Warfare Center Crane Division, (NSWC Crane) has selected Concurrent's fully-integrated iHawk multiprocessor systems running RedHawk real-time Linux for a hardware-in-the-loop (HITL) simulation application.
Currently in development, the missile simulator system will provide input signals to missile guidance hardware in real time, and read the missile's response to provide a closed loop simulation. NSWC Crane is developing the simulator in partnership with multiple DoD labs.
The simulator will be used to determine the effectiveness of Navy and Marine Corps aircraft countermeasure systems that protect the aircraft from hostile missiles. The simulator's roles include optimizing new countermeasures in existing aircraft, determining the best use of existing countermeasures in new aircraft, and evaluating current aircraft capabilities against new missile system threats.
Concurrent's RedHawk Linux allows users to assign real-time simulation tasks to dedicated processor cores. Memory and data are shared between processors with minimal overhead during real-time operation. The solution also provides integration and execution of The MathWorks MATLAB/Simulink models in real time.
"We needed a COTS (commercial off-the-shelf)-based platform solution that could perform real-time analog and digital I/O while easily executing Simulink models," says John Bennett, scientist, NSWC Crane. "We evaluated other alternatives, and selected the Concurrent COTS-based iHawk system with RedHawk real-time Linux based upon our contract requirements."
