Abstract
Various embodiments of methods and systems for managing write transaction volume from a master component to a long term memory component in a system on a chip ('SoC') are disclosed. Because power consumption and bus bandwidth are unnecessarily consumed when ephemeral data is written back to long term memory (such as a double data rate 'DDR' memory) from a closely coupled memory component (such as a low level cache “LLC” memory) of a data generating master component, embodiments of the solutions seek to identify write transactions that contain ephemeral data and prevent the ephemeral data from being written to DDR.
