1. A method for managing write transaction volume from a master component to a long term memory component in a system on a chip (“SoC”), the method comprising: monitoring transactions of one or more master components, wherein the transactions are associated with a closely coupled memory component; filtering the transactions to identify transactions with ephemeral data content, wherein filtering the transactions to identify transactions with ephemeral data content comprises filtering transactions upstream of the closely coupled memory component; and for one or more transactions identified to have ephemeral data content, blocking ephemeral data content from being written back from the closely coupled memory component to a long term memory component; wherein blocking ephemeral data content from being written back from the closely coupled memory component to the long term memory component optimizes bandwidth utilization of a bus.
