【摘要】:介绍了基于龙芯2F的军用嵌入式计算机系统搭载PLX6254桥、LTC1646电源芯片实现CPCI总线的热插拔技术。详细阐述了P1X6254-CPCI桥的硬件接口设计、电源可靠性设计、输入和输出电路的设计以及电源的损耗问题、安全性设计、PCI驱动设计等。实现了将龙芯2F作为可热插拔的PCI从设备挂载到主系统中并能稳定运行的目的。
[Abstract]:This paper introduces the hot-swapping technology of CPCI bus based on PLX6254 bridge LTC1646 power chip in the military embedded computer system based on Longson 2F. The hardware interface design and power supply reliability design of P1X6254-CPCI bridge are described in detail. The design of input and output circuits, the loss of power supply, the safety design and the design of PCI-driver, etc. The purpose of mounting the PCI from the equipment to the main system and running stably by using the Godson-2F as the hot-swappable PCI is realized.
