A hardwired system can fulfil only the purpose for which it was designed. It uses fixed logic gates and chips to perform its given function. Changing the function of the system requires changing circuitry which is an unrealistic proposition in todays fast changing world.. 1. Introduction to ECEn 490. ECEn 490 –Win 2017 Lecture # 1. 2.
