Abstract
A data processing system is described having a central processing unit (CPU) 4, a memory management unit (MMU) 6 and a cache memory 8. The CPU 4 makes cache writes in the same clock cycle that the data is output from the CPU 4. In a following clock cycle, the MMU 6 produces a signal IC indicating whether that storage operation was invalid. If the storage operation was invalid, then a flag associated with a cache storage line storing a plurality of output data words is set to indicate such invalid storage.
