WebTLB organization. The Translation Lookaside Buffer (TLB) is a cache of recently executed page translations within the Memory Management Unit (MMU). The Cortex -X1 core implements a two-level TLB structure. The TLB stores all page sizes and is responsible for breaking these down in to smaller pages when required for the data or instruction L1 TLB.
