Abstract: In an embedded system, there are a plurality of data requesting devices, a plurality of data sources and a bus fabric interconnecting the data requesting devices and the data sources, wherein the bus fabric comprises a plurality of bus components. Some or all of the data sources and arbitration devices associated with the bus components resolve contentions between data bursts by selecting a first one of the contending data bursts; determining a length of a critical section of the first selected data burst; and processing the critical section of the selected data burst. Then, a second one of the contending data bursts is selected, a length of a critical section of the second selected data burst is determined, and the critical section of the second selected data burst is processed before a non-critical section of the selected data burst.
