<p>An apparatus is described for summing the products of a predetermined number of successive pairs of numbers. In the apparatus there is provided an arithmetic unit having a first and a second input and an output, a first, a second and a third register and a first and a second multiplexer. In operation, a first pair of numbers are multipled and the product thereof stored in the third register. Thereafter, a second pair of numbers are multiplied and the product thereof stored in the second register. Thereafter, the contents of the second and third register are added and the sum thereof stored in the third register. After the sum of the products of the first and second pairs of numbers are stored in the third register, the products of succeeding pairs of numbers are stored in the second register. After each such product has been stored in the second register, it is added to the contents previously stored in the third register and the sum thereof stored in the third register until the contents of the third register comprises the sum of the products of all of the pairs of numbers applied to the apparatus.</p> |
