Abstract
Techniques are described for enhancing a hearing assist device using one or more coprocessor devices. The hearing assist device uses a handshaking protocol to detect and pair with the one or more coprocessor devices. The hearing assist device is capable of stand-alone signal processing in the absence of the coprocessor devices. In one embodiment, the hearing assist device directs processing of a signal to the coprocessor device when the coprocessor is detected. In another embodiment, the hearing assist device detects a coprocessor device and uses the coprocessor device to supplement signal processing performed by the hearing assist device. In yet another embodiment, the hearing assist device communicates with a plurality of coprocessor devices and the work of processing the signal is shared amongst the devices according to a respective functionality of each device.
