Abstract

An integrated circuit may include several components, one or more interfaces, an interconnect (e.g., a bus), and a controller. The components may each be configured to assert a read request to read data stored externally to the integrated circuit. The interfaces may be configured to output the read request asserted by one of the components and to receive data in response to outputting the request. The interconnect may be coupled to perform one or more data transactions to transmit the data from one of the interfaces to one or more of the components. In response to the read request asserted by one of the components, the controller may inhibit performance of a read transaction initiated by the read request dependent upon a comparison of a total number of outstanding data transactions to a maximum allowable number of outstanding data transactions.
