REVERSE PULSE COUNTER Russian patent published in 2006 - IPC H03K23/56 H03K23/86 

FIELD: digital computing equipment and automatic devices engineering.

SUBSTANCE: counter performs ops for counting and subtracting pulses, inverting code, adding by module two, logical adding, logical multiplication and parallel receipt of code in triggers. Each bit of counter has one RS-trigger, five AND elements, two OR elements, three NOT elements, five control buses and information bus. Counter forms a transfer potential prior to receipt of counting pulse and builds each bit only on basis of one RS-trigger. Total number of inputs of logical elements of one bit equals 28, in average for one performed operation about four inputs is required.

EFFECT: expanded functional capabilities with minimal equipment costs and increased speed of computations.
