Cache Coherence
Cache coherence is the property of a multiprocessor system in which all processor cores see a consistent, up-to-date view of shared memory data, even though each core maintains its own local cache copies of that data.

What is Cache Coherence in Multiprocessor Systems?
Cache coherence is the guarantee that all CPU cores in a multiprocessor system see a single, consistent view of a shared memory location, even though each core…
Memory-Mapped I/O vs Port-Mapped I/O
Memory-mapped I/O places device registers directly inside the same address space as RAM so the CPU accesses them with ordinary load and store instructions, whi…
What Are the Key Challenges in Multicore Scheduling?
Multicore scheduling is harder than single-core scheduling because the OS must simultaneously reason about cache locality, load balancing across cores, synchro…
