N2 - We will demonstrate a 100-CAR-section cochlear model running in real time on an FPGA. Although our result suggests that an electronic cochlea with 1224 cochlear sections can be implemented on an average FPGA [1], the data rate limit of USB 2.0 does not permit us to implement more than 100 filter sections and display the output on a PC. Future work will explore alternatives to increase the bandwidth such as a PCI interface or USB 3.0 that will enable us to implement more filter sections. Nonetheless, our work demonstrates the capability of the CAR model to process sound in real-time.
