В результате получена таблица прошивки ПЛМ для разделения адресного пространства 64 кБ на 18 несплошных равных частей.
Исходя из требуемого количества произведений ( 18 * 6 = 108 ) и количества выходных функций (18), выбираем в качестве элементной базы выпускаемую фирмой ADVANCED MICRO DEVICES микросхему ПЛМ PLS30S16. Эта микросхема позволяет за счет мультиплексирования четырех адресных входов с выходами иметь от 12 до 17 входов и от 8 до 12 выходов при количестве произведений до 64.
Для решения поставленной задачи берем две ПЛМ, запараллеленные входы которых подключены к шине адреса, а выходы – к входам выбора кристалла соответствующих микросхем.
