Real-time Data Processing for Embedded Systems

In embedded systems, real-time doesn’t just mean fast; it means predictable.

✅ Use interrupts to capture events instantly
✅ Offload transfers with DMA so the CPU stays free
✅ Rely on RTOS scheduling for priority handling
✅ Process data on-the-fly with circular buffers & pre-allocated memory
✅ Always design for worst-case timing, not averages

Real-time = deadlines met, every single time.
