virtual cache - Free On-line Dictionary of Computing (26 May 2007) :

  virtual cache
  
     A cache which uses virtual address, i.e. it is between the
     processor and the memory management unit.  A virtual cache
     cannot recognise external access to physical address, e.g. from
     DMA.  The whole cache must be flushed when swapping between
     tasks which share same virtual address space.
