Store forwarding on the integer side works for all loads contained within a prior store. It’s an improvement over prior arm cores like the Cortex X2, which could only forward either half of a 64-bit store to a 32-bit load. Forwarding on the FP/vector side still works like older Arm cores, and only works for specific load alignments with respect to the store address. Unlike recent Intel and AMD cores, Cortex X925 can’t do zero latency forwarding when store and load addresses match exactly. To summarize store forwarding behavior:

In an ideal situation, such a module has all the parts of code it needs to operate (logic, infrastructure, database access layer, UI). Especially, there should be no shared business logic. Also a module should be able to operate when other modules enter fault mode. In real designs, though, it often turns out that some parts have to be extracted - most often it’s the UI or some infrastructure code or some shared libraries.
