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?

I am told to design a generic microprocessor interface for a ASIC chip. Since I am not familiar with what types/modes of microprocessor are most popular, I don't know how generic I can reach. I am aware of there are synchronous/asychronous modes, separate or mux address/data modes. But I notice there are so many different families and series. Would somebody point me some typical familie...

I have always liked to distinguish a microprocessor from a microcontroller based on whether or not there are integrated peripherals on the same chip or just a CPU. There are some companies that seem to refer to what I traditionally thought of as microcontrollers by the term du jour, System-on-a-Chip. Are these two terms synonymous? Furthermore, sometimes these SOCs are referred to in the sam...
