| Abstract: | The communication speed between ARM and FPGA has a great importance on real-time transmission of acquisition data in multichannel energy spectrum analyzer.Hence this paper applied SPI communication to data transmission between each other.High-speed communication was realized by using SPI interface of ARM owning and programming the SPI modules on FPGA.This approach was tested through simulation and actual applications,the results indicated that the instrument worked normally and stably under high-speed transmission rate.What's more,this SPI communication method possesses well transportability. |
