What we have learnt
- Real-time responses are critical in embedded systems, supporting timely execution of tasks.
- Efficient interrupt handling reduces latency and ensures tasks meet their deadlines.
- Task scheduling algorithms like Rate-Monotonic and Earliest Deadline First play a vital role in prioritizing tasks.
Key Concepts
- -- RealTime Responses
- The ability of an embedded system to process data and respond within a predetermined time frame.
- -- Interrupt Handling
- The method of managing system responses to external events to minimize latency.
- -- Task Scheduling
- The process of assigning priorities to tasks to ensure that more critical tasks are executed first.
- -- Memory Access
- The method of managing how quickly data can be retrieved from or stored to memory in embedded systems.
- -- DMA (Direct Memory Access)
- A feature that allows peripherals to access the system memory independently, increasing efficiency.
