Implementation of High-Speed Serial Communication for Motion Controller Based on DSP and FPGA

FAN De-he,PI You-guo(School of Automation Science and Engineering,South China University of Technology,Guangzhou 510640,China)  
In this paper,a master-slave CNC system that consists of master controller based on ARM,slave controller(motion controller) based on DSP and FPGA was briefly introduced.Based on this,several communication solutions between the master controller and slave controller were discussed and compared in detail.Then,a high-speed serial communication based on RS-485 was proposed.In this solution,a field-programmable gate array(FPGA) chip was used to expand the multi-channel universal asynchronous receiver transmitter(UART) and design double first in first out(FIFO) memories for the data buffering of UART.DSP was used to design software for serial communication.The multi-channel UART steadily operate at 3.125 Mbps with the control of DSP.Test results indicate that the proposed scheme meets the communication requirements between master controller and slave controller in the CNC machine.
