Today’s SOC(System On Chip) due to powerful, inexpensive and totally modern in depth various areas of social life, it’s often used in industrial electronics, consumer behavior, and communications systems, including TV remote control, drinking fountains, elevator and even mobile phones which are visible traces of SOC. Frequency measurement is used to measurement speed, flow rate, and rotary acceleration. However, two frequency measurements which used in industry still have some measurement error. This research is to design one high range high speed frequency counter device which use of ARM(Advanced RISC Machines) Cortex-M0 SOC with microprocessor for catching the locking rising signal. Subsequently, this thesis is to take advantage of accumulated skills and timer interrupt for solving the problem of inadequate resolution and insufficient execution speed. Finally, because of the errors are not the same for all quartz oscillator, it can enter a low-frequency signals in a SOC to correct error. From the above effort, one can apply ARM Cortex-M0 to achieve low cost, high speed approach and to detect the range of 0.0167Hz ~ 250KHz, and the accuracy up to 0.001% of high range high speed frequency counter devices.
