Abstract :
An isomorphic model is introduced to reduce the complexity of the Hopfield model´s digital implementations. To ensure numerical solution with stability and a prescribed accuracy, a mixed-type integration algorithm based on combining a single-step Runge-Kutta method and a multistep predictor-corrector method is applied to the digital simulation of the isomorphic model. A reconfigurable pipeline net VLSI architecture is proposed to implement the mixed-type integration algorithm. The architecture is composed of four processors, a programmable 12×30 routing network, and a 6×n shifter array, which are assigned to deal with the main operations of the integration algorithm, data routing, and synchronization, respectively
