Improving the universality of Design for Control System Using FPGA as Coprocessor

This paper proposes a design scheme of the control system which based on the coprocessor FPGA that can assist the main controller DSP. The system composition and the hardware design are described in detail. Address decoding, bottom high-speed algorithm and data communication are implemented with FPGA. The simulation result is given in this paper. After the program is downloaded in the FPGA chip, the control system works well. Experimental results indicate that FPGA can assist the main controller DSP with the functions of control and communication. This system reduces the complication of DSP design. In most of the control system, this system is universal.
