Neurocomputer with analog signal bus
 An analogue neuron processor (ANP) performs an operation of sum-of-products of a time divisional analog input signal sequentially input from an analog signal bus and weight data and output an analog signal to an analog signal bus through a nonlinear circuit. A layered type or a feedback type neural network is formed of ANPs. The neural network reads necessary control data from a control pattern memory under the control of micro sequencer and reads the necessary weight data from the weight memory thereby realizing a neuron computer. The neuron computer connects a plurality of ANPs by using a single analog bus, thereby greatly decreasing the number of the wires used for the neural network and also decreasing the size of the circuit. A plurality of ANPs in a single layer simultaneously receives analog signal from an analog bus and carries out a parallel operation in the same time period and ANPs in different layers perform a parallel operation in a pipeline manner, thereby increasing a speed of an operation. Accordingly, the prsent invention can provide a neuron computer with a high practicality.
