Abstract :
The applicability of a pyramid architecture, the GAM-2 pyramid computer, for the real-time simulation of dynamic systems is demonstrated. The architecture of the computer and the manner in which data are exchanged between processing elements are discussed. The author focuses on how the differential equations and the various computational units of the integration algorithm can be partitioned among the processing elements at the different levels in the pyramid in order to minimize the computation and data transfer times. The required computation time of an integration cycle is evaluated, and conclusions are drawn concerning the efficiency of using the GAM-2 pyramid and similar structures for digital simulation
