Abstract
A product-sum operation circuit includes a pulse width/digital conversion circuit () which converts a pulse signal having a pulse width representing an operand value into a digital signal, a sorting circuit () which outputs, in descending or ascending order of magnitude, a plurality of operand values Xi converted into digital signals by the pulse width/digital conversion circuit (), and an accumulated sum circuit () which multiplies each operand value output from the sorting circuit () by a corresponding operand value Wi and calculates the accumulated sum of multiplication results. The pulse width/digital conversion circuit () includes a counter () which counts a clock and outputs a count value as a digital signal, and n trailing edge latch circuits (---(n−1)) each of which latches a common count value output from the counter at the trailing edge of the input pulse signal.
