A biomedical multiprocessor SoC for closed-loop neuroprosthetic applications

Successful proof-of-concept laboratory experiments on cortically controlled motor prostheses, brain pacemakers and hippocampal prostheses motivate continued development for neural prosthetic systems. Advances in implantable electrode arrays and miniaturized multichannel recording ICs enable long-duration, wireless and closed-loop experiments on freely moving subjects. To further improve clinically viable neural prostheses, the bulk associated with external systems must be eliminated. Thus a miniaturized processing-and-controlling system interfacing recording ICs and actuators in real time is required.
