摘要
在嵌入式系统设计中,常涉及到ADC的处理问题。文中介绍一种基于FPGA(FieldProgrammableGateArray)的多路ADC(AnalogtoDigitalConvertor)控制转换器,它能够独立地控制多路A/D转换,并能实时地将各路ADC的结果存储到相应的寄存器中。利用该接口控制器能极大地降低ADC对MCU的资源占用,提高嵌入式系统的效率。
During the designing process of embedded system, ADC is always a tough issue. In the paper, controller of multiple ADC based on FPGA was introduced, which can control multiple ADC and store the result of ADC to relevant register real timely. The resource usage of MCU that caused by ADC can be reduced obviously, and efficiency of embedded system was improved.
