IMPLEMENTATION OF REAL-TIME INPUT/OUTPUT INTERFACES AT THE AMRDEC ADVANCED SIMULATION CENTER'S HARDWARE-IN-THE-LOOP FACILITIES

摘要

Hardware in the Loop (HWIL) simulations are often spread over a large area with many hardware and software components. Open and closed loop tests necessitate a flexible test environment of allocating and ordering these components. These components may be connected in a star, a ring configuration, and/or any combinations of these two configurations, with shared memory wrappers connecting some of the software components. A Resource Allocation Program (RAP) is proposed along with a device table to allocate, organize, and document the communication protocol between the software and hardware components. Communication between software components is done through a single set of input output routines using information so that software objects may be changed with hardware objects or placed on different computers with minimal code changes.
