Arbitration method and circuit architecture therefor

摘要

An interconnect system includes an arbitration unit (AU) for arbitration among a plurality of sources or initiators requesting (102) access to resources or targets. The arbitration unit (AU) selectively grants (104) the initiators access to the targets as a function of respective priorities. The system includes a programmable control unit (CU) for programmably choosing the priorities in question out of group of at least two different priority schemes including a positional fixed priority, programmed fixed priority, and a variable priority based on a respective threshold latency values associated to the initiators. <IMAGE>
