In the assembly of the HIL lab bench, we discovered a

lack of tools to perform IIC master operations, which

were required for the target playback. We purchased a

TriCore™ (Infineon Technologies) evaluation board,

adding configuration and software to perform as both an

IIC master and IIC slave between the playback and the

radio. The TriCore has a configurable number of inputs

and outputs (IO), allowing it to be adapted readily to a

variety of playback mechanisms.

Within the virtual radio, we modeled the operating

system (OS) as a Java™ (Sun) executable, running in

the background of the MATLAB process. The OS was

hand-written for this project, based loosely on the

MicroOS™ (Digital Corporation) specifications.
