Множинно-асоціативна кеш пам’ять.

Архітектура множинно-асоціативного кеша дозволяє кожному блоку керованої пам’яті претендувати на один із декількох рядків кеша, об’єднаних в одну множину.

В даному випадку можна рахувати що множинно-асоціативна кеш пам’ять кілька паралельно узгоджених каналів прямого відображення. Контролер пам’яті визначає, який рядок буде міститися у кеш пам’яті.

Індекс, що відображає необхідний блок даних, однозначно визначається середньою частиною адреси (номер рядка в кеші прямого відображення).

Для вибору рядків у склад кеш пам’яті використовується комутатор, який перемикає інформаційні виводи асоціативної пам’яті тегів на коди ініціалізації рядків, які адресуються.

Рис. 1.4

Для цього на вхід адреси комутатора (рис. ) поступає код набору n, а на інформаційні входи комутатора подається унікальний код номера рядка всередині блоку, який визначений у результаті асоціативного пошуку за заданою адресою в тезі. Крім того, з кожним набором пов’язані ознаки, які визначають рядок набору, а також можливість заміщення новим блоком у результаті кеш промаху.

Множинно-асоціативна кеш пам’ять об’єднує принципи кешування з архітектурою прямого відображення та асоціативного, що дозволяє ефективніше використовувати кеш пам’ять.
