Nanosecond threshold logic gates for 16 X 16 bit, 80 ns LSI multiplier

Previous research and development efforts in digital monolithic integrated circuits and arrays were almost exclusively concerned with Boolean logic. However, by introducing threshold logic, considerable savings in gate count as well as in subsystem processing speed are evident. When logic subsystems, such as registers, adders, counters or combinational control logic, designed with common NOR logic, were replaced by subsystems employing threshold logic, average savings in gate count of three to one have been demonstrated. Furthermore, the number of consecutive logic levels necessary to implement a given switching function, and thus the relative processing delay, is also generally reduced by the same ratio.
