Cachet_wrCachet_wr is a module that allows writing to a memory area that is accessed via pages and to which you can write via pages. In order to optimise writing, Cachet_wr offers a write pipeline that is only effective via commit or persist: i.e. the user can write data, but it will be delayed in a pipeline. These writes will only be applied to the memory area after a commit (which flushes our entire write pipeline) or a persist (to flush only part of our pipeline). Reading via Cachet_wr takes this pipeline into account, i.e. after a write, it appears to be effective from the user's point of view but is not actually physically effective.
