Review Questions

• How does throughput relate to task management and scheduling in embedded systems?
  • Throughput is crucial in task management and scheduling because it measures how many tasks can be completed within a specific timeframe. Efficient scheduling algorithms aim to maximize throughput by allocating CPU time effectively among tasks, ensuring that high-priority tasks are processed quickly while also keeping overall system efficiency high. When throughput is increased through effective task management, the embedded system can better respond to inputs and maintain performance levels.
• Discuss the impact of wireless communication protocols on system throughput and how this might affect performance in embedded applications.
  • Wireless communication protocols like Bluetooth and Wi-Fi play a significant role in determining system throughput because they define the rate at which data can be transmitted. Factors such as signal strength, interference, and protocol overhead can all reduce the effective throughput achieved in real-world applications. Consequently, optimizing these protocols and understanding their limitations is critical for embedded applications where performance heavily relies on timely data transmission.
• Evaluate how emerging technologies may influence throughput in future embedded systems designs.
  • Emerging technologies like 5G networks, advanced caching techniques, and AI-driven optimization algorithms are poised to significantly enhance throughput in future embedded systems. As these technologies allow for faster data processing and improved resource allocation, they will enable systems to handle larger volumes of data with minimal latency. This evolution could lead to new applications that require real-time data handling, thus raising expectations for throughput in diverse embedded scenarios.
