Description
Technical field
The present invention relates to the technical field of computer interface, is a kind of adapter for 3UCPCI-Ex8 bus interface specifically.
Background technology
The full name of CPCI-E is CompactPCIExpress (CompactPeripheralComponentInterconnectExpress), it is a kind of new bus interface standards that International Industry Technological Problems In Computer Manufacturing person federation (PCIIndustrialComputerManufacturer'sGroup the is called for short PICMG) CPCI that continues (CompactPeripheralComponentInterconnect) issued in 2005.CPCI physical construction tool has the following advantages: 1, durability.CPCI uses DIN connector (the pin hole connector of 2mm density), has reliability, stability, anti-corrosive properties and high load capability.2, shock resistance.Guide rail support is all arranged at CPCI card top and bottom, together with front panel is screwed with cabinet.Even if therefore in violent impact and vibrations occasion, lasting connection and can not loose contact also can be ensured.3, hot-swappable.Adopt the pin contact pin of three kinds of different lengths, make under the condition of system not power-off, board can normally insert or extract, thus does not destroy the normal work of system.
The full name of PCI-E is PCIExpress (PeripheralComponentInterconnectExpress), is a kind of bus interface standards proposed in calendar year 2001 by Intel.For replacing the third generation I/O technology of pci bus, be called as " 3GIO ".In field of interconnects, PCI-E bus interface achieves transmission mode by the change of low speed single-ended parallel bus to high-speed differential serial bus.PCI-E tool has the following advantages compared with pci bus: 1, data line is few.Serial interconnection fashion, relative in parallel mode, greatly reduces transmission line quantity thus saves wiring space.2, transmission speed is fast.Compare pci bus and share parallel architecture, PCI-E adopts all external units of connected mode end to end to have independently data transmission channel, without the need to whole bus request bandwidth, thus can improve the transfer rate of data.Can only realize one-way transmission relative to traditional PCI bus within the single clock cycle, the two single work of PCI-E connects can provide higher transfer rate and quality, difference therebetween with half-duplex and full duplex similar.3, antijamming capability is strong.Compared with PCI single-ended parallel signal transmission form, PCI-E differential signal transmission effectively can suppress electromagnetic interference (EMI), reduces the mutual interference in signal wire transmitting procedure, and improving bus should antijamming capability to external world.
The complete compatible with PCI of CPCI-E bus-E bus inferface protocol, inherit the physical construction advantage of cpci bus technology simultaneously, while breakthrough Signal transmissions bandwidth sum distance limit, ensure that integrality and the Electro Magnetic Compatibility of signal, add carrying load ability and the antijamming capability of bus, achieve the high reliability of bus, expansibility and strong durability.Based on above characteristics and advantages, CPCI-E bus interface technology has a very wide range of applications in the field such as military and industrial.
But, due to the employing of PCI-E interface card is golden finger interconnection structure, cannot directly dock with the European pin hole connector that CPCI-E system adopts, and PCI-E bus interface does not possess features such as adding solidity, durability, reliability and vibration resistance, cause CPCI-E interface card directly cannot be applied in 3UCPCI-E and reinforce in cabinet.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of adapter for 3UCPCI-Ex8 bus interface.
The technical scheme that the present invention takes for the technical matters existed in solution known technology is:

The present invention also can adopt following technical measures:
Described input connector inputs a road PCIEX8 bus, and out connector exports 5 road PCIEX8 buses.
The model of described main control chip is PEX8648.
The model of described configuring chip is AT25128.
The advantage that the present invention has and good effect are:
1. durability: CPCI-E uses European pin hole connector, and this connector has the features such as high reliability, high stability and carrying load ability are strong.
2. shock resistance: the drawing-aid device using band self-locking, board inserts drawing-aid device after cabinet and can be automatically locked, and only has manually to press unlock button and can extract board.
3. extendability: PCI-Ex8 connector is standard interface, meets PCI-E bus standard agreement, so be applicable to all kinds of Standard PC I-Ex8 board.User only needs to change PCI-Ex8 interface card, and the application of the invention just can the different 3UCPCI-E board of practical function, is applicable to various standard 3UCPCI-E and reinforces cabinet, greatly reduce R&D cycle and cost.
4. ease for use: the present invention meets structure and the electric requirement of standard 3UCPCI-E board, follows CPCI-E bus standard agreement, so be applicable to each class standard 3UCPCI-E to reinforce cabinet.
