The Design and Implementation of a Control Computer Based-on FPGA Core

According to the requirement of the system operation, a control computer monitors and controls a large number of key nodes, synthesizes a variety of excitation signals, obtains the angular state of the rotating mechanism, controls its rotation to the specified position. Based on an FPGA (Field-Programmable Gate Array) core, this paper develops a signal synthesizing module, a digital axis-angle conversion module and a W5500 Ethernet interface using a SOPC system that can be tailored and configured flexibly. It integrates the customed logic IPs into the SOPC (System-on-a-Programmable Chip) system of the Nios II architecture. The software system coordinates the operation of all modules. Finally, the control computer synthetically implements all its functions.
