* Question
What are the architectures of embedded systems?
* Answer
Embedded systems architectures can be broadly classified into several types based on their design and operational characteristics. Here are the main architectures:
1. Single Microcontroller/Microprocessor Architecture:
– Single Chip: The entire system is built around a single microcontroller or microprocessor that handles all tasks.
– Features: Simple, cost-effective, suitable for small-scale applications with limited functionality.
2. Multi-Microcontroller/Microprocessor Architecture:
– Multiple Chips: Multiple microcontrollers or microprocessors are used, each handling different tasks or subsystems.
– Features: Increased performance and functionality, more complex design, suitable for larger and more complex applications.
3. System on Chip (SoC):
– Integration: Combines all components of a computer or other electronic system into a single integrated circuit (IC).
– Features: High integration, reduced size, power-efficient, commonly used in mobile devices, IoT devices, and complex embedded systems.
4. Real-Time Operating System (RTOS) Based Architecture:
– RTOS: An operating system specifically designed to manage hardware resources and run applications with precise timing constraints.
