The first stage in the EDLC (Embedded Development Life Cycle) is requirements gathering. Once the requirements gathering is done, the objectives of designing the system are to be identified. Then we need to design the architecture or the block diagram of the embedded system. Then the detailed design of each block is to be made which will be then implemented as a prototype.

The coding or the embedded programming is the next stage wherein the programming of the system is to be done. Then the testing of the designed system will be done. The testing is a very important phase. There will be various possible inputs that will be given to the system to be tested and based on that the correctness of the system designed will be known. During this testing phase, there may be some improvements required in the prototype, which will be updated accordingly to repeat the designing, coding etc.

Once the system is perfectly tested and found to have no problems, then in it is developed, implemented to be delivered. The system is then in operation.
