LSI microprocessors and microprograms for user-oriented machines
Imsong Lee · 1974
The fundamental aspect of microprogramming as introduced by Wilkes in 1951 [1,2] is the implementation of sequential control with stored or programmed logic in contrast to hardwired random logic involving adhoc connections of large numbers of simple logic gates. The microprogramming became practical with the availability of high speed memories at reasonable cost during the 60s and has become a very popular tool even for the design of small, low-cost computers.
