Floating-point DSP with rich peripherals and higher frequency is widely used in the field of industrial control. The field bus constituted by CAN bus and high-speed communication network composed of Ethernet have become the develop-ment hot points in the field of industrial control. A design method of the interconnected system for Ethernet and CAN bus based on TMS320F28335 is proposed in this paper. The design and implementation methods of the hardwares and softwares in each as-sembly of the system are presented. The TMS320F28335 of TI Company is adopted in the control section. SN65HVD230 of TI Company is adopted as CAN bus interface module. RTL8019AS of Realtek Company is taken as the control chip of Ethernet in-terface module. The design has the advantages of good scalability and high cost performance.
