That looks seriously disturbed. Normal filesystems have a backing store
plus a page cache. Tmpfs removes the backing store and keeps everything
in the page cache. XIP removes the page cache and leaves everything in
the backing store - which is memory.
Would tmpfs plus XIP remove both the page cache and the backing store?

Data dominates. If you've chosen the right data structures and organized
things well, the algorithms will almost always be self-evident. Data
structures, not algorithms, are central to programming.
