摘要
通过对LBS控制器的控制信号、LBS总线读写操作时序、LBS状态机进行分析,设计并实现了一个高效、可靠的LBS控制器来实现FPGA和PEX8311的通信系统,在PEX8311和FPGA接口中运行状态正常,稳定性强,成功应用于某视频采集卡、某PCIe数据采集卡等,基于FPGA设计的LBS控制器具有灵活性强、可编程能力强、适应性强等优点。
Through analyzing the control signal of LBS controller,reading and writing operation sequence of LBS bus and LBS state machine,an efficient,reliable LBS controller is designed to achieve the communication between FPGA and PEX8311.It has high stability and normal state running in FPGA interface and PEX8311,which is successfully used in some video capture card and PCIe card.The FPGA-based LBS controller has features of flexibility,programmable ability,adaptability,etc.
