Fpga Design For Monitoring Canbus Traffic In A Prosthetic Limb Sensor Network

This paper presents a successful implementation of a Field Programmable Gate Array (FPGA) CANbus Monitor for embedded use in a prosthesis device, the University of New Brunswick (UNB) hand. The monitor collects serial communications from two separate Controller Area Networks (CAN) within the prosthetic limb's embedded system. The information collected can be used by researchers to optimize performance and monitor patient use. The data monitor is designed with an understanding of the constraints inherent in both the prosthesis industry and embedded systems technologies. The design uses a number of verilog logic cores which compartmentalize individual logic areas allowing for more successful validation and verification through both simulations and practical experiments.
