【摘要】：介紹了基于龍芯2F的軍用嵌入式計(jì)算機(jī)系統(tǒng)搭載PLX6254橋、LTC1646電源芯片實(shí)現(xiàn)CPCI總線(xiàn)的熱插拔技術(shù)。詳細(xì)闡述了P1X6254-CPCI橋的硬件接口設(shè)計(jì)、電源可靠性設(shè)計(jì)、輸入和輸出電路的設(shè)計(jì)以及電源的損耗問(wèn)題、安全性設(shè)計(jì)、PCI驅(qū)動(dòng)設(shè)計(jì)等。實(shí)現(xiàn)了將龍芯2F作為可熱插拔的PCI從設(shè)備掛載到主系統(tǒng)中并能穩(wěn)定運(yùn)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.
