translation lookaside buffer การใช้

• The R2000 chip contained a small translation lookaside buffer for mapping virtual memory addresses.
• The SBus controller had its own 16-entry input / output translation lookaside buffer.
• This is called the translation lookaside buffer ( TLB ), which is an associative cache.
• The I-box contains two translation lookaside buffers ( TLBs ) for translating virtual addresses to physical addresses.
• Its translation lookaside buffer ( TLB ) and cache architecture are different from all other members of the MIPS family.
• The R4200 has a 32-entry translation lookaside buffer ( TLB ) for data, and a 4-entry TLB for instructions.
• The R4000 has an advanced translation lookaside buffer ( TLB ) where the entry contains not just virtual address but also the virtual address space id.
• This can lead to distinct TLBs for each access type, an Instruction Translation Lookaside Buffer ( ITLB ) and a Data Translation Lookaside Buffer ( DTLB ).
• This can lead to distinct TLBs for each access type, an Instruction Translation Lookaside Buffer ( ITLB ) and a Data Translation Lookaside Buffer ( DTLB ).
• There are different replacement methods like Least recently used ( LRU ), First Come First Out ( FIFO ) etc ., See the Flowchart shows the working of a Translation Lookaside Buffer.
• The Supervisor bit is overloaded to represent NX . This causes a protection fault when access occurs to the page " and " it is not yet cached in the translation lookaside buffer.
• The fast path through the MMU can perform those translations stored in the translation lookaside buffer ( TLB ), which is a cache of mappings from the operating system's page table, segment table or both.
• This approach differs from multiprocessing, as with multithreading the processes and threads share the resources of a single or multiple cores : the computing units, the CPU caches, and the translation lookaside buffer ( TLB ).
• When accessing this 1 MiB memory, each of the 256 page entries would be cached in the translation lookaside buffer ( TLB; a cache that remembers virtual address to physical address translations for faster lookup on subsequent memory requests ).
• Before Phenom's original release a flaw was discovered in the translation lookaside buffer ( TLB ) that could cause a system lock-up in rare circumstances; Phenom processors up to and including stepping " B2 " and " BA " are affected by this bug.
• The backup translation buffer was essentially a translation lookaside buffer ( TLB ) which handled a miss in the MTB . The BTB contained 512 page table entries ( PTEs ), of which 256 were for system-space pages and 256 were for process-space pages.
• Quite similar is " " ", where the memory management unit ( MMU ), which is used to translate virtual addresses to physical addresses, has a working set of more pages than can fit in its cache, the translation lookaside buffer ( TLB ).
• Other types of caches exist ( that are not counted towards the " cache size " of the most important caches mentioned above ), such as, the common to all modern CPUs, the translation lookaside buffer ( TLB ) that is part of the memory management unit ( MMU ) that most CPUs have.
• The P2SC was not a complete copy of the POWER2, the L1 data cache and data translation lookaside buffer ( TLB ) capacities were halved to 128 KB and 256 entries, respectively, and a rarely used feature that locked entries in the TLB was not implemented in order to fit the original design onto a single die.
