Структурная схема работы сопроцессора состоит из тех же блоков, что и ЦП. Основное отличие: отсутствует блок запросов прерываний и АЛУ предназначено для операций над числами с ПТ

Выводы

Был разработан однокристальный RISC процессор общего назначения.

Для него была разработанна

1 Регистровая модель процессора

2 Регистровая модель сопроцессора

3 Система команд

В процессе разработки мы ознакомились с такими понятиями как:

Виртуальная память

Форматы данных

Форматы команд

Сопроцессор (назначение и организация функционирования)

       Так же была разработана программа моделирующая работу процессора и показывающая особенности доступа и обработки данных во обоих возможных режимах (пользователь/ супервизор).
