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}.
