microcode would be software = small code
microprocessor would be hardware = small processor
One has little to do with the other.

Yes, it has been done.
What happens in these chips is that one instruction is executed per clock.
For certain signal processing applications, this is ideal, because you want speed, above all else.
You would not use this architecture for a generalpurpose computer. It is not flexible enough.

By the way.
With microcode, a processor breaks down the assembly/machine code into smaller steps, and executes them, to get the effect of the assembly instruction.
A processor with no microcode, just feeds the instruction into it's instruction decoding logic array, a clock pulse occurs, and the logic gates, that are enabled, determine what happens, the instruction is done. One Step. No intermediate steps.
