  Translation Look-aside Buffer
  TLB
  
     <storage, architecture> (TLB) A table used in a virtual memory
      system, that lists the physical address page
     number associated with each virtual address page number.
     A TLB is used in conjunction with a cache whose tags are
     based on virtual addresses.  The virtual address is presented
     simultaneously to the TLB and to the cache so that cache
     access and the virtual-to-physical address translation can
     proceed in parallel (the translation is done "on the side").
     If the requested address is not cached then the physical
     address is used to locate the data in main memory.  The
     alternative would be to place the translation table between
     the cache and main memory so that it will only be activated
     once there was a cache miss.
