Transaction Integrity

The transaction protocol is a monitor for integrity. If the data beat count is not correct, or there are other irregularities, then an interrupt is asserted.

The protocol integrity of the incoming AXI transactions are monitored by the interconnect iPorts. The following table lists the integrity violation features.

Table 1. iPort Protocol Integrity Checker Detection
Violation Detection Operation Next Step
Illegal AXI transaction incoming Detection is done by the transaction packet consistency check (part of safety features) Normally requires an interconnect reset
Missing/extra data word beats Detection is done by the transaction packet consistency check (part of safety features) Normally requires an interconnect reset
Act as the master proxy to complete pending transactions All mechanisms are for detection only, not handled
