  primary cache
  L1 cache
  level 1 cache
  level one cache
  
     <hardware, architecture> (L1 cache, level one cache) A small,
     fast cache memory inside or close to the CPU chip.
  
     For example, an Intel 80486 has an eight-kilobyte on-chip
     cache, and most Pentiums have a 16-KB on-chip level one
     cache that consists of an 8-KB instruction cache and an 8-KB
     data cache.
  
     The larger, slower secondary cache is normally connected to
     the CPU via its external bus.
