+description: |
+    The Bus Clock Manager (BCM) is a dedicated hardware accelerator
+    that manages shared system resources by aggregating requests
+    from multiple Resource State Coordinators (RSC). Interconnect
+    providers are able to vote for aggregated thresholds values from
+    consumers by communicating through their respective RSCs.
