Abstract
In order to provide an inexpensive binary data counting device of which the processing is done at high speed and which can be implemented with a small circuit scale, a shifter array is provided for outputting binary data of N bits, which comprises N×(N+1)/2 shifters of which the control inputs are the data expressed in a binary manner comprising N bits so that binary data wherein is are filled in from the right in the same number as 1s in the data expressed in a binary manner comprising N bits are outputted by controlling the operation of each shifter in the shifter array with each bit value of the data expressed in a binary manner comprising N bits. An encoder is also provided for converting said binary data into a multi-valued number in accordance with the position of 1 in said binary data on the MSB side.
