ABSTRACT:
A method of operating a bus interconnect coupled to bus masters and bus slaves is provided. The method includes receiving a request from a bus master to perform a bus transaction associated with a transaction ID with a bus slave of the plurality of bus slaves, the bus transaction being a first type of bus transaction. The method further includes performing the transaction if a resource allocation parameter allocated to the bus master meets a first threshold. The method further includes if the resource allocation parameter does not meet the first threshold, performing the data transaction only if the transaction meets a condition of a set of at least one condition, wherein a condition of the set of at least one condition includes that the transaction ID of the transaction is not a transaction ID of any outstanding bus transaction of the first type requested by the bus master.
