Embedded systems

A dedicated computing system (microcontroller or microprocessor) integrated into a larger device to execute one or a few specific, real-time functions.

Embedded systems are specialized computational units: a combination of hardware (like an ARM Cortex-M microcontroller) and firmware, designed for a dedicated function within a larger mechanical or electronic system. They operate under tight constraints—cost, power, and size—and often require real-time processing to control physical operations via sensors and actuators. Applications are everywhere: from a simple digital watch to complex automotive Electronic Control Units (ECUs) and industrial IoT devices. The market is robust, valued at $110.3 billion in 2023, with growth driven by continued investment in AI and mobile computing integration. We’re talking about the core intelligence for nearly all modern electronics.
