Memory accesses are among the most complicated and performance critical operations on a modern CPU. For each memory access, the load/store unit has to translate program-visible virtual addresses into physical addresses. It also has to determine whether loads should get data from an older store, or from the cache hierarchy. Cortex X925 has four address generation units that calculate virtual addresses. Two of those can handle stores.
