Evaluation of Delfino (TMS320F28379D) Processor for Helmet ANC Application

Embedding Active Noise Control (ANC) system to fighter aircraft helmet imposes size constraint for the controller board as it needs to be integrated inside ear cup. Further ANC system development needs to take place under stringent weight and power constraints. Selection of a suitable processing platform plays a key role in meeting the requirements. This paper proposes to use TMS320F28379D, a microcontroller with DSP capabilities. Evaluation is done by carrying out single channel ANC simulation. Also, the size, weight and power consumption of the ANC controller achievable with this processor is worked out to ascertain that it can be integrated into the helmet.
