ABSTRACT:
A crossbar switching circuit and operating method thereof for coupling a plurality of source providers to a plurality of source consumers based on the request of the source consumer are provided. The crossbar switching circuit includes a plurality of source consumer terminals coupled to the source consumers respectively, a plurality of source provider terminals coupled to the source providers respectively, a plurality of first counters and a plurality of second counters. Wherein, each source consumer terminal has one first counter and one second counter. The first counter indicates a current latency state of the resource requested by the corresponding source consumer. The second counter indicates a current bandwidth state of resource requested by the corresponding source consumer. In addition, the connecting states between the source consumer terminals and the source provider terminals are determined based on the states of the first counters and the second counters.
