Embedded systems usually consist of hardware and software specifically tailored to the needs of the device or product. The hardware used in embedded systems is usually compact and low-power, while the software is integrated into the device's firmware and stored in non-volatile memory. This allows the system to start and run automatically without the need for a separate operating system or user intervention.
The software used in embedded systems is designed to have a high degree of automation so that minimal human interaction is required to control or monitor the device or product. The software is usually written in low-level programming languages such as C or assembly language and must be optimized for the specific hardware used in the system. This optimization is important to ensure that the system runs efficiently and reliably under demanding conditions.
