Adapter card from PCI (Peripheral Component Interconnect) Express X1 to CPCI (Compact Peripheral Component Interconnect) Express X1

Abstract

The invention relates to an adapter card from PCI (Peripheral Component Interconnect) Express X1 to CPCI (Compact Peripheral Component Interconnect) Express X1, which can be used for converting a PCI Express X1 slot in a commercial and industrial control desk computer into a CPCI Express X1 slot meeting a PICMG (PCI Industrial Computer Manufacturers Group) EXP.0R1.0 standard so that a CPCI Express X1 interface card (expansion card) meeting the PICMG EXP.0R1.0 standard can be applied, debugged and tested in the PCI Express X1 slot in a common commercial and industrial control desk computer. The adapter card comprises an impedance control circuit board, a PCI Express interface, a CPCI Express signal socket, a double-row hole socket, an adapting circuit board, a connecting block, a bending double-row plug, a CPCI Express power supply socket and a baffle plate. The invention has the advantages and effects of not influencing the quality and effect of signals in the PCI Express X1 and the CPCI Express X1, expanding the application of the traditional PCI Express X1 slot to ensure that the traditional PCI Express X1 slot is compatible with the CPCI Express X1 interface card (expansion card), greatly reducing the difficulty and the cost of the development of the CPCI Express X1 interface card (expansion card) and having simple structure and convenient use.

Description

technical field [0001] The invention relates to a PCI Express X1 to CPCI Express X1 adapter card, which is used to convert a PCI Express 1 slot in a computer into a CPCI Express X1 slot conforming to the PICMG EXP.0R1.0 standard, so as to conform to the PICMG EXP. The 0R1.0 standard CPCI Express X1 card can be applied, debugged and tested in the PCIExpress 1 slot. The invention belongs to the fields of computer communication, computer aided testing and automatic testing. Background technique [0002] PCI Express is a new generation of computer serial bus, which replaces the traditional synchronous or asynchronous sequential logic bus interface with a protocol. It has high transmission rate, saves hardware resources, no crosstalk, no intersymbol interference, no signal offset, no DC bias and other outstanding features. Therefore, once launched, it has been widely valued and applied. At present, all kinds of commercial computers and industrial control computers have PCI Exp...

AI Technical Summary

Problems solved by technology

However, due to the difference between CompactPCI Express and PCI Express standard connectors and interface definitions, the CompactPCI Express interface board cannot be directly applied, debugged and tested in the PCI Express system (computer)

In other words, the current PCI Express system is not compatible with CompactPCI Express interface boards (expansion cards)
