:Indeed. Properly speaking microcode is used to impliment an instruction set, but from the 1960's IBM referred to VLIW code used for other purposes as microcode. Further, on the low end [[IBM System/360]] and [[IBM System/370|S/370]] machines, IBM used the same hardware instruction set to simulate the architect instructions and to implement the I/O channels.
:To add to the confusion, other terms have been used for code and instruction sets used to simulate another instruction set, e.g., ''logand'' and ''logram'' on the [[TRW]]-130; see [http://www.bitsavers.org/pdf/trw/trw-130/ bitsavers] for manuals.
