I then develop or update components such as startup code, BSPs, drivers, interrupt handling, and initialization routines, validating each layer with hardware-assisted debugging and targeted tests. How do you investigate a real-time performance or determinism issue? I first define the timing requirement and capture evidence through tracing, instrumentation, and debugger data. I examine interrupt latency, task priorities, synchronization, cache effects, contention, and execution paths, then make measurable changes and verify worst-case behavior under representative load. What are important considerations when developing for ARM-based multicore processors? Key considerations include memory coherency, cache management, core affinity, interrupt routing, inter-core communication, synchronization primitives, and shared-resource contention. I aim to minimize nondeterministic interactions and verify that the design remains correct under concurrent execution. Describe your approach to hardware and FPGA software integration. I work from interface specifications and register maps, establish basic communication and initialization early, and use incremental tests to validate each interface. I collaborate closely with hardware and FPGA engineers to isolate whether defects arise from timing, configuration, signal behavior, drivers, or the underlying design. How would you support DO-178C-oriented software verification activities? I would maintain clear traceability from requirements through design, implementation, and verification evidence. I would support reviews, develop testable code, document assumptions, perform unit and integration testing, analyze coverage where required, and ensure anomalies are recorded and resolved through the defined process.
