| Abstract: | A SOPC method for measuring the digital frequency meter is designed. This method configures the embedded soft-core MicroBlaze microprocessor and encapsulates the AIX frequency measurement and the measured duty-cycle IP core to transmit the data to the soft-core processor to complete the system function. MicroBlaze calculates the data and controls the system. The system was validated at Dgilent"s Basys3 board. The results show that the system is accurate, stable, simple program and low cost through the test. The design fulfills the expected results and verifies the feasibility of the program. |
