In embedded design, digital logic can be applied in the following ways：
1. Logic gate design: Utilize logic gates such as AND, OR, and NOT to construct specific functional circuits to achieve the processing and control of input signals.
2.State machine design: Control the behavior and operation sequence of the equipment by defining different states and state transition logics.
3.Encoding and decoding: For example, binary encoding of data or decoding of input signals to extract useful information.
4.Signal processing: Use digital logic to perform shaping, filtering and other operations on the signals collected by the sensor.
5.Control logic design: Design complex control logics to coordinate the work of various modules, such as the start, stop, and mode switching of the equipment.
6.Timing logic design: Ensure that the system executes operations in the correct time sequence, such as the generation and distribution of clock signals.
7.Data path design: Construct the path of data flowing and processing in the system, including the selection, storage, and operation of data.
8.Fault detection and fault tolerance: Utilize digital logic to implement fault detection mechanisms and fault-tolerant processing logics to improve system reliability.
9.Interface design: Design digital logic to handle interface signals with external devices or other systems.
10.Encryption and security: Use digital logic to implement encryption algorithms and security mechanisms to protect data and the system.
