Key Components of an Embedded System
An embedded system typically consists of:
- Microcontroller/Microprocessor – The brain of the system.
- Memory – ROM, RAM, or Flash for storage and runtime execution.
- Input/Output Interfaces – Sensors, displays, buttons, communication modules.
- Embedded Software – Firmware programmed for specific operations.
🔍 Characteristics of Embedded Systems
- Task-Specific: Designed to perform a particular operation or set of tasks.
- Real-Time Performance: Fast and consistent response times for critical operations.
- Low Power Consumption: Essential for battery-operated or compact devices.
- Compact & Efficient: Often built to be small and efficient in size and processing.
- Reliability: Mission-critical systems require long-term performance without failure.
