Abstract
A device for checking numbers consists of a multiplexer () with a controller module () linked to it. An output of the multiplexer is connected to a first input of a register (), which is an element of memory, while a first output of the controller module () is connected to an input of a storage () and a second input of the register (). An output of the register () and an output of the storage () are connected to inputs of the adder (), which adds on its output a number, stored in the register () and a number written in the storage () at an address indicated by the controller module (). The adder () generates on its output a carry-out signal, informing about overflow, which is passed to a first controlling input of the controller module (), which manages operation of the device checking numbers. A second controlling input of the controller module () is coupled a logical NOR type gate () passing a zero signal informing that the number on the output of the adder () equals zero.
