Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Devise a system where dynamic memory allocation is essential. Describe how you would implement bounds to ensure its safety in real-time operations.

💡 Hint: Consider using techniques to limit the size of each allocation.

Challenge 2 Hard

Analyze a scenario where an embedded application failed due to unmanaged memory leading to ISR delays. What strategies could have been applied to avoid this issue?

💡 Hint: Think about proactive strategies.
