Ah, nice move. Back to your usual habits?
Prefetching would not change anything here. The problem come
from variable size encoding, and the challenge it causes for
hardware. You can have 100% L1 hit and still have the same
problem.
There is _no_ cache. The compiler fully controls the layout of
the scratchpad.
That's hardware 101.
Is it?
The core point is this:
1. if there is academic interest (i.e. publishing opportunities)
you get research
2. if there is research you get new algorithms
3. you get funding
etc
You cannot predict at this point what the future will be like. Is
it unlikely that anything specific will change status quo? Yes.
Is it highly probable that something will change status quo? Yes.
Will it happen over night. No.
50+ years has been invested in floating point design. Will this
be offset over night, no.
It'll probably take 10+ years before anyone has a different type
of numerical ALU on their desktop than IEEE754. By that time we
are in a new era.
