The Interface Design of Ultrasonic Phased Array Detection and Imaging System Based on ARM+FPGA

The ultrasonic phased array detection and imaging system is built, and the two communication interfaces are designed based on ARM (Advanced RISC Machine) and FPGA (Field-Programmable Gate Array). The logical connection mode of FPGA and ARM is designed, the working mode of M9K in FPGA is configured, and the transfer and transmission of the system configuration and the echo data are realized through the dual port system. The device driver is written under the Linux operating system, the operation and control of the ARM to the FPGA are realized, and the interaction between the hardware and the software is completed. The system is tested through the experiment. It runs normally and the results are correct which meets the design requirements.
