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)

Abstract

The invention discloses an adapting card for peripheral component interface (PCI) Express X16 to compact peripheral component interconnect (CPCI) Express X16. The adapting card comprises an impedance control circuit board, an adapting circuit board, a PCI Express X16 interface, a CPCI Express signal socket, a CPCI Express power socket, a double-row hole socket, a bent pin double-row plug, a connecting block and a baffle plate, wherein the CPCI Express signal socket and the adapting circuit board are connected with the upper part of the impedance control circuit board; a PCI Express X16 interface is formed in the lower part of the impedance control circuit board; the bent pin double-row plug is arranged on the left middle part of the impedance control circuit board; and the CPCI Express power socket and the bent pin double-row plug are arranged on the adapting circuit board. The quality and the efficiency of a signal are not affected, the application range of the current PCI Express X16 slot is expanded, the difficulty and the cost for the development of a CPCI Express X16 interface card are greatly reduced, and the adapting card is simple in structure and convenient to use.

Description

technical field [0001] The present invention relates to a kind of adapter card that is used for PCI Express X16 to CPCI Express X16, is used for converting the PCI Express X16 slot in the computer into the CPCI Express X16 slot that conforms to PICMG EXP.0R1.0 standard, so that conforms to PICMG The CPCI Express X16 card of EXP.0R1.0 standard can be applied, debugged and tested in the PCI Express X16 slot. The invention belongs to the fields of computer communication, computer aided testing and automatic testing. Background technique [0002] PCIExpress 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...
