We intend to complete a testbed environment that is appropriate to the scope of the entire proposal. This testbed will complement the two other more specialized testbeds designed for the applications in Thrust area V: The NSWC's Bremerton Detachment and the ARL's Battlefield Acoustic Signal Processing Testbed. This testbed is a computerized electronic interface to prototypes that we develop. In this environment, we will have the ability to swap between a software simulation module, a breadboard or DSP module, and in certain instances, a custom VLSI chip. The heart of the testbed is a substantial computer with substantial I/O capability. At the most basic level, the interface will allow testing and debugging of new board designs and chips. The interface will also allow that a software procedure can be replaced by the computer communicating with a newly-built device. The computer will also carry the burden of executing the recognizer software. Signals delivered to the test bed will include the helicopter gearbox data from NASA Lewis, Sonar data from the Naval Surface Systems Center, and speech data from standard datasets. These data will be maintained in a database of our own design that is available to the broader research community. We will use a standard data format for both the hardware and software systems so that signals and test results can be shared between the teams working on software models and those working on hardware models.
