TLBFlushes
The Translation Lookaside Buffer (TLB) is a hardware cache that stores recent virtual-to-physical memory address translations. TLB flushes are operations that clear or invalidate entries in this cache, which becomes necessary when memory mappings change. These operations occur during context switches, when page tables are modified, or when virtual memory systems are reconfigured.
TLB flushes can be selective, targeting specific entries, or global, clearing the entire buffer. The frequency
Modern processors implement various TLB management techniques to minimize performance impacts, including hierarchical TLBs with different
