| Abstract: | The design of dual-access RAM which can realize data communication between two CPUs in main shaft controllers of magnetic suspension is introduced. By virtue of complex programmed logical data (CPLD), dual-access RAM is designed based on the combination of graphics and VHDL. In the designing process, the conflict of the two CPUs in writing operation at the same time is solved using the data logical method. This design is successfully applied in main shaft controllers of magnetic suspension. |
