A PARALLEL PROCESSOR NETWORK, A PROCESSOR AND A METHOD FOR SOLVING DIFFERENTIAL EQUATIONS IN A PARALLEL PROCESSOR NETWORK

摘要

The present invention relates to a parallel processor network, a processor and a method for solving differential equations in a parallel processor network. A parallel processor network includes several processors (processing units) that are arranged in a regular form. A processing unit is coupled with selected processing units. A problem for integrating this kind of a parallel processor network into a chip is the minimization of the physical size and power consumption of the processor. In the parallel processor network of the invention, the couplings are realized with analog multipliers. The sum of analog couplings is converted to a digital quantity that is used to digitally integrate the state(s) of a processing unit. The state(s) are converted to an analog quantity that is used to control the analog multipliers. The invention allows the minimization of the power consumption and physical size of the paralles processor network.
