System mainboard for embedded computer systems

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...

AI Technical Summary

Problems solved by technology

At present, the APCI5000 series embedded industrial control machine adopts the Compact PCI bus technology. The bottom board has only one system slot and a single CPU board. Its performance has been greatly improved, but it is required for high system reliability and computer performance. In the field of aerospace, its reliability and performance need to be improved

[0017] At the same time, the rapid development of modern aerospace science and technology requires a substantial increase in the data processing capabilities of aerospace computers, but the current domestic aerospace computers cannot meet such high requirements. Therefore, the research and development of computer motherboards based on high-performance CPUs seems to be especially necessary
