... and that leads me to another idea.

<imagination on>

Has anybody ever thought about data triggered software
concepts?

If a single processor today has to do a thing twice, it
must run the programm sequentially two times, one after
another with different data. In this case instruction
caches will only bring additional power (beside burst
loading) if the code completely fits into the cache.
Otherwise it may be faster without cache, since reload
always adds penalty.

The processors usually run a program that has to fetch
data, modify it and store it somewhere. This is a code
(program) focused solution.

The other way I can imagine is a data focused solution.
The availability of data triggers the execution of a
code part for that data to modify it. That could lead
to a completely event triggered software scheme, i.e.
data triggers software, which generates data, which
triggers software a.s.o.

Since this is a very basic mechanism it could be run
on a single processor and on multiple processors. Or
on the nearest processor available...
It's not the same as task switching because it takes
place on a much lower level. And it may obsolete task
switching concepts like they exist today.
