Digital Filter for Cochlear Implant Implemented on a Field- Programmable Gate Array

The advent of multi-million gate Field Programmable Gate Arrays (FPGAs) with hardware support for multiplication opens an opportunity to recreate a significant portion of the front end of a human cochlea using this technology. In this paper we describe the implementation of the cochlear filter and show that it is entirely suited to a single device XC3S500 FPGA implementation .The filter gave a good fit to real time data with efficiency of hardware usage. Keywords—Cochlea, FPGA, IIR (Infinite Impulse Response), Multiplier.
