I cannot really understand the relation between the length of programs and the use of hardwired/microprogrammed control units.
few points I thought about.
if we have only small length of programs then will have less complexity of the hardwired circuit.because of less number of instructions.
but having small length programm doesnot guarantee us that we will have less number of instructions .In total we might have a large number of different instructions.(making the circuit complex )
if we have large length programs then we will have more complexity of the hardwired circuit.because of more number of instructions.
but having large length program doesnot guarantee us that we will have large number of instructions .In total we might have a programs using only a small set of instructions.thus less hardwire required.
so the length of program doesnot determine the which type of control unit to use.
