Additional Reference bits algorithm

Here we keep an 8-bit byte for every page in memory. At standard intervals the reference bit is shifted by the OS. If a shift register contains 00000000 then the page hasn't been used for the last 8 time periods. A page with a history 11000000 is more recently used than 01000000. The no of bits are able to be varied accordingly to the needs of the OS.
