摘要
介绍了一种基于ISA接口的航空总线ARINC429接口板的实现方案。其中,用TI公司的TMS320F206作为板卡的嵌入式CPU,有效地提高了板卡的执行速度,简化了外围电路的设计。译码、控制和中断逻辑用Altera公司的CPLD实现,提高了板卡的集成度。实验表明:该板卡满足高速ARINC429数据传输要求,有执行速度快、集成度高、体积小、可靠性好等优点。
A scheme of realization of interface card of ARINC 429 based on ISA bus is introduced. In this scheme, TMS320F206 of TI company is used as the embedded CPU of this card. The performing speed is efficiently improved and the design of periphery circuit is simplified. CPLD is used to realize the logic of coding, controlling and interruption. By this way, integration of this card is improved. The expermental result shows that it satisfies the requirement of the transmission of ARINC 429 data with high speed and has the virtue of high performing speed, good integration, small volume, strong reliability and so on.
