microprocessor that improves as they progress

Just wanted to know. Is it possible for a microprocessor (so the
software) to improve their performance over period of time? Can
microprocessor improve its performance as they progress/continue to
work? If not, what we need to do to achieve this? could this be
implemented in silicon? Is it worth doing? Is there any research in
progress?

Write a better compiler. About 10 years ago, several of the SPEC benchmarks
were boosted by a quite significant amount by clever compiler tricks. So my
Pentium became 20% faster over night - at least if you looked at the SPEC
results.

You also can make application programs faster over time, running on the same
processor.

No, the "aging" of silicon will make your processor slower over time, not
faster. You can do that only in software.

What you are refering to is known as either AI or heuristics - software
that learns over time by interacting with its environment.

Sure, by adding a cache.

Google "machine learning"

no. It is not about AI/heuristics/machine learning.

neither cache memory.

Anyhow, it will take microprocessor one machine cycle to execute "move
r1 r2". My question is, is it possible for a microprocessor to make
more than one moves in a machine cycle or to make one move in less than
one machine cycle.

Perhaps a more relevent question is "Why has my code suddenly developed 
timing problems?"

Some virtual machines already improve program execution over time.  I  
don't see why a programmable microprocessor can't do the same.

Yes.  Many architectures provide a 'swap' instruction that does just that.

Generally speaking, simple instructions can complete long before the cycle  
ends, but then have to wait for the next clock transition.  Unless you  
have a clockless architecture, of course.

Vijay,

It seems you've asked two questions between your two posts. This more
recent question is really just a matter of architecture and
parallelism.

However, I do think that AI, or possibly reconfigurable computing is an
appropriate answer to your original post. Aside from caching and
inherent parallelism in the architectures themselves, effective
improvement of hardware can be accomplished via the enhancement of
algorithms and data sets (AI), or literally reconfiguring the hardware
to accomplish the most relevant instruction-execution architectures for
the current data (RC).

The line between hardware and software optimization is inherently
blurry here, as it well should be.

Sure.  Many use zero cycles to do a swap.  All it is is a pointer 
change.  The data goes nowhere.

Certainly.  The one I work on can complete five instructions per 
clock cycle. 

> or to make one move in less than one machine cycle.

Some processors take zero cycles for some ops (like your swap).
