Abstract
A reconfigurable processing unit for a digital hearing instrument includes an IS processor module, a plurality of processing units and a crosspoint switch matrix. The IS processor module receives a hearing instrument configuration. Each of the processing modules are configured to process audio signals received by the digital hearing instrument. The crosspoint switch matrix is coupled to the IS processor module and each of the processing modules, and includes at least one crosspoint switch that is configured to route audio signals between processing modules and to combine at least two audio signals. In addition, the IS processor module uses the hearing instrument configuration to program the configuration of the crosspoint switch and thereby control how the crosspoint switch matrix routes and combines audio signals.
