Abstract

The system mainboard for embedded computer includes one CPU chip, one sync DRAM chip, one starting chip, one flash memory chip, FPGA chip, etc. and all the chips perform communication via data bus and address bus. The system mainboard also has definied X port and X port bus, and the X port bus is connected to double serial port and spare starting chip outside the system mainboard. The system mainboard is connected to embedded computer based on COMPACT PCI bus and X port bus structure. The high performance computer mainboard of the present invention has powerful function, powerful processing capacity, small size and moderate power consumption, and is suitable for use in aeronautics, astronautics and other fields with high processing capacity requirement.

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...
