【摘要】：介紹了基于龍芯2F的軍用嵌入式計算機系統搭載PLX6254橋、LTC1646電源芯片實現CPCI總線的熱插拔技術。詳細闡述了P1X6254-CPCI橋的硬件接口設計、電源可靠性設計、輸入和輸出電路的設計以及電源的損耗問題、安全性設計、PCI驅動設計等。實現了將龍芯2F作為可熱插拔的PCI從設備掛載到主系統中并能穩(wěn)定運行的目的。
[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.
