Description: Design based on FPGA alarm system.
1. The second module is actually a counter that records and outputs one second.
2. On the basis of a pulse rise along the count, the module added time adjustment control.
3. Adjust the control module of the time to realize the adjustment of time when the signal is effective.
4. Alarm clock adjustment and control module can realize the adjustment function of alarm setting.
5. Display module, realize the switch between time and alarm display.
6. Alarm module to realize alarm sound device.
7. General logic module, to realize the corresponding function of electronic alarm system.
-FPGA-based alarm system design. 1. Second module is actually a counter, a second recording and output. 2. Am, when the module is a pulse based on the rising edge of a count by adding the time to adjust control. 3. Adjust the time of the control module, the enable signal is active in order to achieve the hours of adjustments. 4. Alarm clock adjustment and control modules can be realized when the alarm clock set up regulatory function. 5. Display module to realize the time and alarm clock display switch. 6. Alarm module to achieve the alarm audible signal devices. 7. The total logic block to realize the corresponding function of the total electronic alarm system.
