摘要
采用EZ-USB FX2技术,设计开发了基于USB2.0的海床基自动监测平台数据接口方式。采用三态双向门电路控制存储器模块总线复用实现数据访问;采用直接内存读写方法完成数据传输;采用参数存储器完成参数设置。实验证明在数据传输、参数设置以及低功耗控制方面取得良好效果,提高了系统工作性能。
The technology of EZ-USB FX2 was introduced to design and develop a type of USB2.0 data interface. The data memory access was implemented by bus duplicated using tristate bidirectional gate; the data transter was accomplished by DMA （Direct Memory Access） method ; the parameters were set by parameters-storage. The,experiment had shown that data transfer, parameters setting and the control of low power-consumption had been carried out effectively and the performance of ASMP system had been improved.
