Welche dieser Definitionen zutrifft, hängt vom jeweiligen Kontext ab, wobei auch hier die Übergänge fließclose sind.
Microcode is really a Particular, reasonably obscure type of embedded software which tells the processor itself tips on how to execute equipment code, so it is definitely a lower level than device code. It is typically proprietary to your processor company, and any vital correctional microcode software updates are equipped by them to buyers (which is less expensive than delivery replacement processor hardware). Thus a standard programmer would not assume to ever have to cope with it.
