Title: Design and implementation of FPGA based communication architecture for control system
Abstract: A high efficiency communication architecture applied in distributed control system (control system inner extending bus) was proposed to realize highly-efficient transmission and real-time control,and the design of its bus interface and bus protocol was detailed.The communication architecture,which is mainly consisted of field-programmable gate array (FPGA),complex programmable logic device (CPLD) and ARM7 CPU,implements hot swap on the target with high-speed transmission characteristics.As to the bus interfaces,the dual-channel and parallel communication method increase the system's transmission efficiency,and the redundancy between the two channels helps enhance the reliability of the communication.As to the bus structure,the highly-efficient secondary buffer and electrical expansion make the system very flexible.This communication architecture was put into effect on a system prototype,and the results show that it has high real-time performance and highreliability.
