ACS Real-time/embedded systems development Competency Level Interrupt handlers, context switching, and memory-mapped I/O aren’t abstract concepts at this level—they’re daily tools. Before tackling this exam, you need hands-on experience with at least one RTOS, familiarity with interrupt priorities and ISR design patterns, and the ability to diagnose timing violations in resource-constrained environments. Without that foundation, the hardware-software interaction questions will expose gaps quickly.
