Computing device for performing digital pulse-based crossbar operation and method of operating the computing device

A method of operating a computing device that includes a plurality of input lines, a plurality of output lines crossing the input lines, and a plurality of elements respectively disposed at cross points between the input lines and the output lines, comprising:

• selectively inputting a respective pulse to each of the input lines according to a corresponding input signal in a sequential manner;
• transferring, by each of the elements to a corresponding output line, the respective pulse from a corresponding input line in response to a corresponding weight being a first value and a corresponding selection signal being received, including overlapping the corresponding selection signal in time with the respective pulse and ceasing the corresponding selection signal after cessation of the respective pulse;
• and
• counting, by a plurality of pulse counters that are each disposed in a respective output line, a respective number of pulses resulting from the transferring to the respective output line.
