Abstract
У деяких варіантах здійснення винаходу багатокаскадний фільтр, каскади біквадратних фільтрів якого об'єднані з затримкою між каскадами, система (наприклад, аудіокодер або декодер), що включає такий фільтр, і способи багатокаскадної біквадратної фільтрації. У типових варіантах здійснення винаходу всі каскади біквадратних фільтрів фільтра діють незалежно з метою виконання повністю розпаралеленого оброблення даних. У деяких варіантах здійснення винаходу багатокаскадний фільтр згідно з винаходом містить буферну пам'ять, щонайменше два каскади біквадратних фільтрів і контролер, підключений і сконфігурований для затвердження єдиного потоку команд у каскадах фільтрів. Як правило, багатокаскадний фільтр є сконфігурованим для виконання багатокаскадної фільтрації на блоці вхідних дискретних значень у єдиному циклі оброблення даних з повторенням за індексом дискретних значень, але без повторення за індексом каскадів біквадратних фільтрів.
