Description

technical field

[0001] The invention relates to a computer system mainboard, in particular to a system mainboard of a high-performance and high-reliability embedded computer system used in the fields of aviation and aerospace. Background technique

[0002] Compact PCI technology is a small and sturdy high-performance bus technology based on the standard PCI bus. In 1994, PICMG (PCI Computer Manufacturer's Group, PCI Industrial Computer Manufacturers Alliance) proposed Compact PCI technology, which defined a more robust and durable version of PCI. It is fully compatible with the PCI standard in terms of electrical, logic and software.

[0003] Compact PCI boards have the following features:

[0004] PCI local bus

[0005] Standard Eurocard size (according to IEEE 1101.1 mechanical standard)

[0006] HD (High Density) 2mm Pin and Socket Connectors (IEC Approved, Bellcore)

[0007] 1. PCI local bus

[0008] PCI stands for Interconnection of Peripheral Devices. Released by...
