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; and for one or more transactions identified to have ephemeral data content, preventing the ephemeral data content from being written back from the closely coupled memory component to a long term memory component; wherein preventing the 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.
