+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.
