TLB flush

In a chip's memory, hidden from view, Lies a cache that's quite clever, called the TLB, It stores translations, oh so grand, From virtual memory to physical land. When accessing memory, oh so fast, The TLB reduces time, it's a blast, An address-translation cache, you see, Helping us reach memory, oh so free. Between CPU and cache, it resides, Or between cache and memory, it hides, In multi-level cache, it may be found, In processors, it's always around. Sometimes, it's a content-addressable memory, With virtual address as the search key, you see, If a match is found, oh what a delight, A TLB hit, everything's alright. But if the address is not in the TLB's space, A page walk begins, at a slower pace, Reading memory contents, oh so fine, To compute the physical address, quite divine. So remember the TLB, a memory's friend, Helping us access, from beginning to end, In processors it's always there, Making virtual memory, oh so fair. Random page: CW-17R Pursuit Osprey
