Embedded System – Salient Features & Characteristics

Definition: Embedded system is a dedicated computer + software hidden inside a product to perform specific control/monitoring.

Salient Features:

  1. Single/defined function - optimized for one task.
  2. Real-time operation - must respond within deadlines (hard/soft real-time).
  3. Resource constrained - limited memory, CPU, power.
  4. Reliability & stability - long uptime without failure.
  5. Low cost, small size, low power - mass-produced.
  6. Hardware-Software co-design - tightly coupled.
  7. Interactive & reactive - responds to sensors/environment.
  8. Microcontroller/SoC based - integrates CPU, memory, I/O on chip.

Characteristics:

  • Application specific, firmware in ROM/Flash.
  • Minimal UI or headless.
  • Uses cross-development tools.
  • Often has no or small OS (RTOS).
  • Must tolerate temperature, EMI as per deployment.
  • Examples differentiate from general-purpose computer which is programmable for many tasks.
