Abstract
Изобретение относитс к вычислительной технике и может быть использовано при построении процессоров цифровой обработки сигналов. Цель изобретени - расширение функциональных возможностей за счет выполнени одномерных и двумерных преобразований Фурье и Хартли. Это достигаетс за счет того, что в состав устройства вход т блоки пам ти 1, 2, блоки посто нной пам ти 3, 4, коммутаторы 5 - 9, регистры 10 - 13, сдвиговый регистр 14, регистры 15, 16, сумматор-вычитатель 17, умножитель 18, генератор тактовых импульсов 19, счетчик 20, триггер 21, блоки элементов ИЛИ 22, 23, элементы ИЛИ 24, 25, регистр 26. 3 ил.The invention relates to computing and can be used in the construction of digital signal processing processors. The purpose of the invention is to expand the functionality by performing one-dimensional and two-dimensional Fourier and Hartley transforms. This is achieved due to the fact that the device consists of memory blocks 1, 2, blocks of permanent memory 3, 4, switches 5-9, registers 10-13, shift register 14, registers 15, 16, adder-subtractor 17, multiplier 18, clock pulse generator 19, counter 20, trigger 21, blocks of elements OR 22, 23, elements OR 24, 25, register 26. 3 Il.
