Title:
積和演算装置
Document Type and Number:
Japanese Patent JP6876220
Kind Code:
B2
Abstract:
In each of analog circuits 11 in a multiply-accumulate operation device 10, electric charges, each of the electric charges having a size depending on each of values of N+ electric signals and each of values of positive loads corresponding to the N+ electric signals, are held in a first capture-and-storage means 19, electric charges, each of the electric charges having a size depending on each of values of (N-N+) electric signals and each of absolute values of negative loads corresponding to the (N-N+) electric signals, are held in a second capture-and-storage means 27, a sum of N+ multiplied values obtained by multiplying each of the positive loads corresponding to the N+ electric signals by each of the values of the N+ electric signals respectively is calculated when detecting that a voltage held in the first capture-and-storage means 19 reaches a first threshold, a sum of (N-N+) multiplied values obtained by multiplying each of the absolute values of the negative loads corresponding to the (N-N+) electric signals by each of the values of the (N-N+) electric signals respectively is calculated when detecting that a voltage held in the second capture-and-storage means 27 reaches a second threshold, and a sum of N multiplied values is obtained by subtracting the sum of (N-N+) multiplied values from the sum of N+ multiplied values.
