Challenge Problems

Push your limits with challenges.

Question 1

Consider an embedded system using pipelining. If two instructions cause a structural hazard due to resource sharing, what approaches could be adapted to address the issue? Provide examples.

💡 Hint: Think about how resources can be managed effectively to minimize stalls.

Question 2

In a multi-core system utilizing processor-level parallelism, discuss the implications of cache coherency when different cores have their caches. How would you address potential issues?

💡 Hint: Consider the mechanisms that maintain data consistency across multiple caches.
