Data Integrity

data_integrity_check

AMBA AHB Protocol Specification ARM IHI 0033C ID090921

Transaction data inconsistent with subordinate memory.

Checks that data in transaction is consistent with data in memory when the transaction completes. This checks that a WRITE transaction issued by a manager is written to memory correctly. Similarly, it checks that a READ transaction fetches the correct data from memory. The check assumes that a transaction issued by a manager completes only after response is received from the subordinate to which that transaction was routed. It also assumes that there is no other transaction that accesses an overlapping address during the period that the response is issued by the subordinate and the transaction completes in the manager that issued the transaction.
Note that this check is not performed on the transactions that are routed to the default subordinate.
