AMBA interconnect (AMBIX)

The AMBA interconnect (AMBIX) is a multilayer-capable bus interconnect that provides low latency access from Managers to Subordinates.

Manager and Subordinate connections are arranged in Manager and Subordinate pairs, allowing for a sparse bus matrix. The interconnect supports multiple concurrent transactions when targeting different Subordinates.

Some peripherals do not have the opportunity to pause incoming data. Being a low priority bus manager might cause loss of data for such peripherals upon bus contention. To avoid bus contention when using multiple bus managers, follow these guidelines:

Avoid situations where more than one bus manager is accessing the same RAM subordinate.
If more than one bus manager is accessing the same RAM subordinate, make sure that the bus bandwidth is not exhausted.
