摘要：
This method comprises:
selecting, depending on an address of a word to be read or written, a first cell in an indirection table and using, as first value generated for a line index, the value contained in this first cell, and
in response to triggering of a cache miss:
storing the word retrieved from a memory of higher rank in a new line identified by a second line-index value, this second value being contained in a second cell of the indirection table, and
permutating, in the indirection table, only values contained in the first and second cells, so that after this permutation the first cell contains the second value and the second cell contains the first value.
