基于ETX模块的机载数据处理模块的设计

摘要

针对目前嵌入式系统通常采用基于芯片的设计模式,给出了一种基于模块的嵌入式设计方案在使用ETX模块基础上,通过FPGA将PCI总线转换成LBE和IDE总线,对ETX模块的功能进行了扩展.在短时间内设计出符合要求的产品,集成度高,实现了小型化设计.验证表明设计方案合理可行,在提升系统性能的同时,具有可靠性高,配置灵活,通用性强等特点.%A new design- method based on electronic module is proposed to supersede the usual design method based on chip in embedded system. This method extends the function of ETX module by converting PCI bus to LBE bus and IDE bus through FPGA based on ETX. A system module with high integration and miniaturization has been made to meet the requirement by using this kind of method in a short time. Verification shows that the design is reasonable and feasible, and has features of high reliability, flexible configuration and best configuration.
