High-density Electrical Data Acquisition System Design Based on NIOSII
This paper designs embedded high-density electrical data acquisition system on SOPC technology.The system realizes synchronous control of three-channel AD7760 with 24 A/D to implement electrical analog signal digital digital conversion function,by configureing Nios Ⅱ soft core CPU and some corresponding interface modules on a FPGA to construct the module’s hardware and by combing software are programming. Addition, using CY7C6801 as the control chip,the system meetsStheSrequestSof theShighSspeed ofSdataStransmission in order that
