Applications of a microprogrammed microprocessor
A. J. Nichols · 1974
FOR MINIMUM SYSTEM COST, A MICROPROGRAMMED APPROACH IS OFTEN VERY ATTRACTIVE, THIS IS PARTICULARLY TRUE WHEN THE APPLICATION IS RESTRICTED TO MINIMUM MEMORY REQUIREMENTS, IN SUCH CASES IT BECOMES FEASIBLE TO COMBINE MICROPROCESSOR, CONTROL MEMORY, AND DATA STORAGE ON A SINGLE MOS/LSI CIRCUIT AND THUS ACHIEVE MINIMUM COST, THE MOST PREVALENT EXAMPLE OF SUCH SYSTEMS TODAY IS THE HAND-HELD CALCULATOR AND THE MICROPROGRAMMED LSI APPROACH PROVIDES THE IDEAL SOLUTION TO A DIFFICULT ENGINEERING TASK.
