随着现代汽车电子技术的发展,车身电子控制器件数目不断增加,整车控制系统的复杂度与生产成本不断提高,简化车载电子连接线束与降低汽车设计成本的要求促使副总线技术(LIN总线)应运而生。本文提出一种基于FPGA芯片的LIN总线节点控制器IP核设计方法。基于FPGA技术的设计具有开发周期短、研发成本低的特点。另外,FPGA技术支持动态化下的可重构性应用,同时,大量已成熟的可应用FPGA资源, With the development of modern automotive electronic technology, the number of body electronic control devices has been increasing, the complexity and cost of vehicle control systems have been increasing. The demand for simplifying automotive wiring harness and reducing vehicle design costs has driven the development of secondary bus technology (LIN bus) Came into being. This paper presents a FPGA-based LIN bus node controller IP core design method. FPGA-based design has the characteristics of short development cycle and low R & D cost. In addition, FPGA technology supports the reconfigurability of applications under dynamic, while a large number of mature FPGA resources available,
