ABSTRACT:
A method of caching data is provided, which includes a plurality of processes1602to1605, a cache manager813and a data type register805including at least one data type1901and a corresponding data type bit1903. Said data type bit1903is set (1904) within the register805on being accessed by each of said processes and subsequently reset (1905) within the register. The cache manager813restores (1501) each of said set data type bit and identifies its corresponding data type1901. The cache manager writes the output data1609, 1610, 1611of each of said processes1603, 1604, 1605within a memory cache2001and said cache manager resets (1505) said memory cache2001when the data type bit set by the last of said processes1602is reset.
