Embedded software is specialized computer software designed to operate hardware devices that are not general-purpose computers. It is embedded as an integral part of a complete system, providing the control, monitoring, and user interface required by the device. It may run on microcontrollers, digital signal processors, or application processors and often operates under real-time constraints.

Key characteristics include constrained resources such as limited memory and storage, restricted processing power, and energy considerations. Reliability and deterministic behavior are essential, particularly in safety-critical or mission-critical applications. Embedded software often has long lifecycles and needs secure firmware updates and robust fault handling.

Architecture typically stacks firmware at the lowest level, device drivers, a real-time operating system or bare-metal scheduler, middleware, and the application layer. The software is tightly coupled to the hardware and may be optimized for a family of devices with shared peripherals and interfaces.

Development practices emphasize cross-compilation, hardware-in-the-loop or emulation, and extensive testing. Debugging commonly uses JTAG or SWD interfaces, and verification relies on static and dynamic analysis, unit tests, and integration tests. Development standards such as MISRA C in automotive, ISO 26262, or IEC 62304 in medical devices are applied to improve safety and quality.

Deployment and maintenance involve bootloaders, secure over-the-air or local updates, and configuration management. Security, reliability, and traceability are central concerns, with attention to boot security, encryption, and secure coding practices.

Embedded software spans sectors such as consumer electronics, automotive, industrial automation, aerospace, and medical devices, and continues to evolve with trends toward edge computing, AI at the edge, and increased connectivity. Its effective design is critical to the performance and safety of many modern devices.
