Motion controllers and simulation systems including motion controllers

摘要

A motion controller including a computer comprising a primary processor or a central processing unit and an input/output communication bus. The primary processor is in communicative connection with the bus and is adapted to communicate with other devices in communicative connection with the bus via the bus. The motion controller also includes at least one secondary processor in communicative connection with the bus. The secondary processor is adapted to execute at least one control algorithm for one or more axes of motion associated therewith. The secondary processor is further adapted to communicate with other devices in communicative connection with the bus via the bus independently of the primary processor (that is, the secondary processor is can effect bus mastering). The operating system of the computer can, for example, be a general purpose operating system.
