Field Programmable Gate Arrays (FPGAs) provide flexible computational architectures that are ideal for digital signal processing (DSP). With support of a NIH/NIDCD SBIR grant*, we are developing an open FPGA platform for the speech and hearing research community where one of the objectives is to develop open hearing-aid and cochlear processors. The advantage of the FPGA computational platform over conventional CPU approaches is the ability to implement low-latency high-performance signal processing with deterministic latencies.
The hardware portion of the platform includes audio I/O, an audio codec, and an Intel FPGA with flexible I/O. Development of signal processing algorithms uses Mathwork’s Simulink, which allows exploration and modeling of signal processing algorithms. Once a Simulink model has been developed, VHDL code can be generated that implements the signal processing in the FPGA fabric where the FPGA functions as a real-time signal processor.
We are currently soliciting ideas/feedback from the speech and hearing community as to what features they would like to see in the next iteration of the open FPGA-based computational platform.
