Abstract
This paper proposes a real-time bioinspired visual encoding system for multielectrodes’ stimulation of the visual cortex supported on Field Programmable Logic. This system includes the spatio-temporal preprocessing stage and the generation of varying in time spike patterns to stimulate an array of microelectrodes and can be applied to build a portable visual neuroprosthesis. It only requires a small amount of hardware which is achieved by taking advantage of the high operating frequency of the FPGAs to share circuits in time. Experimental results show that with the proposed architecture a real-time visual encoding system can be implemented in FPGAs with modest capacity.
