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, and its performance has been greatly improved. , aerospace field, 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

Embodiment Construction

[0073] The technical solutions of the present invention will be described in detail below in conjunction with specific embodiments of the present invention.

[0074] An embedded computer system adopts a computer hardware structure with a base plate and 6 plug-in cards. Its mechanical appearance is a standard PCI 8U structure, and 6 plates are installed vertically. As shown in Figure 1, an embedded computer system 10 includes a base plate 20 , a first system main board 30 , a -1394 interface board 40 , an Ethernet interface board 50 , a power supply / control board 60 , a digital signal processing interface board (DSP interface board) 70 and a second system main board 80 . The backplane of the computer system and each board inserted into the slot of the backplane will describe its structure and specific implementation in sequence below.

[0075] In the standard Compact PCI structure, each backplane can have up to 8 slots, one of which is a system slot, which is plugged into the s...

Abstract

The embedded computer system based on COMPACT PCI structure includes one back board, the first system mainboard, the second system mainboard and one power supply / control board, and the two system mainboards and the power supply / control board are inserted in the slots of the back board. The two system mainboards are backed up mutually, and the system controls the signal level vian its control logic in the power supply / control board so as to control the master-slave relation between two system mainboards. The present invention adopts design and reconfiguration technology based on COMPACT PCI bus structure, redefines the COMPACT PCI specification and has starting chip BOOTROM BAK in the power supply / control board for starting back-up, so that the computer system has raised processing capacity and performance and raised stability.

Description

technical field [0001] The invention relates to an embedded computer system, in particular to a high-performance and high-reliability computer system applied in the field 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 connector (IEC approved, Bellcore) [0007] 1. PCI local bus [0008] PCI stands for Interconnection of Peripheral Devices. Released by Intel in 1992, it soon becam...
