Application of High-speed Serial Communication to the Electric Propulsion Control System Based on FPGA

This paper introduces a modified Differential Manchester Encoding method, and studies the implementation of this method in the serial communication. The encoding method is realized by VHDL programming, and the simulation verification is accomplished on Quartus II, and the test carried out on a FPGA circuit board shows that this method has high reliability. By studying the existing serial communication protocol and referencing the International Standard IEC 60044-8, this paper brings up an user-defined protocol which balances the encoding efficiency and programming complexity. Through the study of current situation of the electric propulsion control system, and comparing with traditional serial communication technology, this method has great distribution. advantage in signal collection and control signal distribution.
