Embedded Engieering PPT - September (1).pptx
- 1. Introduction to Embedded Engineering Embedded engineering combines hardware and software to create intelligent devices. These devices can be found everywhere, from smartphones and cars to medical equipment and industrial machinery.
- 2. Hardware Design Principles 1 Microcontrollers The brain of embedded systems, they execute instructions and control devices. 2 Sensors Gather data about the environment, providing input to the microcontroller. 3 Actuators React to commands from the microcontroller, controlling physical elements. 4 Power Supply Provides energy to operate the system, often using batteries or external sources.
- 3. Microcontroller Architecture Central Processing Unit (CPU) Executes instructions and performs calculations. • Arithmetic Logic Unit (ALU) • Control Unit Memory Stores data and instructions. • Program Memory (ROM/Flash) • Data Memory (RAM) Peripherals Interface with the outside world. • Timers • Serial Communication (UART, SPI) • Analog to Digital Converters (ADC)
- 4. Embedded Software Development 1 Requirements Analysis Define the system's functionalities and constraints. 2 Software Design Develop a software architecture and choose programming languages. 3 Coding and Testing Write code, test, and debug to ensure functionality. 4 Deployment Install the software on the microcontroller and configure settings.
- 5. Real-Time Operating Systems Task Scheduling RTOS manage and prioritize tasks to ensure efficient execution. Inter-task Communication Allow tasks to share data and synchronize their actions. Resource Management Control access to shared resources, such as memory and peripherals. Time Management Provide precise timing for critical tasks, ensuring real- time performance.
- 6. Debugging and Testing Techniques Hardware Debugging Use tools like oscilloscopes and logic analyzers to analyze signals. Software Debugging Employ breakpoints, logging, and tracing techniques to identify errors. Simulation and Emulation Test software behavior without needing physical hardware. Functional Testing Verify system functionality against defined requirements.
- 7. Trends and Future Directions in Embedded Systems Internet of Things (IoT) Connecting devices to the internet for data sharing and remote control. Artificial Intelligence (AI) Integrating AI algorithms into embedded systems for decision- making. Cloud Computing Offloading processing and storage to cloud services for scalability and flexibility. Cybersecurity Protecting embedded systems from malicious attacks and data breaches.
