Philipp,

There are tons of embedded systems benchmarks on the internet. In our
compiler work we have found the most informative benchmarks are application
type benchmarks close to the actual intended application.

The application fragment type benchmarks (fft, filters, math packs) are
useful generally is seeing how focused a compiler is in optimizing a
specific application area.

Generic benchmarks would likely need to also have some definition of the
intended application area.

There isn't much meaning in comparing the performance of processors used in
mice and processors used in home appliance controllers. Both are non hosted
embedded controllers with a few K of code but very different requirements.
They may even be members of the same family.
