Multilayer perceptron with on-chip learning using stochastic ratio pulse arithmetic

The necessity of the hardware implementation of neural networks is discussed. However, it is difficult to realize compact operators into a small silicon area. Therefore we used the ratio pulse method in stochastic arithmetic, and the representation of the ratio of ones and zeros in its random pulse stream. The ratio method has the advantage that it reduces the size of operators in neural networks. This paper proposes learning algorithms, using ratio pulse arithmetic, for an on-chip neural network with circuits
