Method Detail

_residentRange

protected MemoryRange _residentRange(int asid,
                                     long address)
                              throws MemoryAccessException

Throws:

MemoryAccessException

findWhichMemoryRange

protected static int findWhichMemoryRange(int asid,
                                          long addr,
                                          MemoryRange[] ranges,
