Abstract
A data processing system is disclosed in which a store has a plurality of pairs of storage locations. An indicator is provided for each location pair to indicate which location of the pairs is to be used for read and write accesses. The indicators are each set to indicate that after a write access to a pair of locations, read accesses are to take place to the location of the pair currently indicated for write accesses and periodically, for example at the end of a sequence of instructions, the indicators are set to indicate that write accesses are to take place to the opposite location of the pair to that which is currently indicated for read accesses.
