In order to facilitate the man-machine interactive operation of high precision impedance analyzer and the data communication between ARM and DSP dual-core processor,the extended keyboard for man-machine interactive operation was designed,which having ARM taken as the control system,and FPGA-assisted dual port RAM based to realize data communication between double CPUs;meanwhile,the interface driver design under Linux communication was elaborated.Experimental results show that this design scheme can be applied to high precision impedance analyzer effectively and steadily.
