3UCPCI multifunctional one-board computer

Abstract

The invention belongs to the technical field of computers, specifically belongs to the field of embedded one-board computers and particularly relates to a one-board computer integrated with various bus multifunction modules. The one-board computer comprises a shell, a processor, a complex programmable logic device, a local bus and a peripheral interface, wherein the processor, the complex programmable logic device, the local bus and the peripheral interface are arranged on a circuit board in the shell; the complex programmable logic device and the local bus are mutually connected and are respectively connected with the processor; the local bus is also connected with a 1553B bus and an ARINC-429 bus; the local bus is connected with the peripheral interface through the 1553B bus; one end of the ARINC-429 bus is connected with the peripheral interface, and the other end of the ARINC-429 bus is connected with the local bus through a field-programmable gate array. According to the one-board computer provided by the invention, on the basis that combination functions of three computer integrated boards are realized, by matching a storage element and interface equipment, the three computer integrated boards are integrated, and therefore, the 3UCPCI multifunctional one-board computer is realized; meanwhile, the goals that the power consumption is reduced, space is saved and the cost is reduced are achieved.

Description

technical field [0001] The invention belongs to the technical field of computers, specifically to the field of embedded single-board computers, and especially refers to a single-board computer integrated with multiple bus multifunctional modules. Background technique [0002] At present, for a computer system with a main processor board, 1533B bus and 429 bus, three kinds of computer integrated boards are usually used together. port, two 422 / 232 serial ports; 1553B bus board QCP-1553-1, 2 channels, 429 bus board RAR-Cpci-8, 8 channels; a total of three computer integrated boards are required. If there are limitations on the size and low power consumption of the computer, using a three-plate computer structure will result in high power consumption and a large footprint, which will increase the cost.
