Title:
MULTIPLIER-ACCUMULATOR
Document Type and Number:
WIPO Patent Application WO/2018/034163
Kind Code:
A1
Abstract:
A multiplier-accumulator 10, wherein, using an analog circuit 11: charges having dimensions that correspond to the values of positive loads and electrical signals constituting N + pairs are held in a first storage means 19; charges having dimensions that correspond to the values of absolute values of negative loads and electrical signals constituting (N-N+) pairs are held in a second storage means 27; the sum of N+ multiplication values derived by multiplying each of the positive loads corresponding to each of the values of N+ electrical signals is calculated when the voltage held in the first storage means 19 is detected to have reached a first threshold value; the sum of (N-N+) multiplication values derived by multiplying each of the absolute values of the negative loads corresponding to the values of each of (N-N+) electrical signals is calculated when the voltage held in the second storage means 27 is detected to have reached a second threshold value; and the sum of (N-N+) multiplication values is subtracted from the sum of N+ multiplication values to obtain the sum of N multiplication values.
