Multi-micro processor-array: EHW for a control system

This paper introduces the Multi-Micro Processor-Array (MMPA) as a kind of Evolvable Hardware (EHW) for an industry control system. At first it describes one of the traditional methods, logic method, for the reconfiguration of a system. Then it applies an evolutionary algorithm to improve the reconfiguration so that the architecture of the control system can be configured dynamically and optimally. The evolutionary algorithm is executed in the structure of the MMPA. Relationship among the components and tasks is employed to speed up searching solutions. Physically the bus connects the microprocessors that form an array. Logically the microprocessors construct a ring: token ring. The microprocessor that gets the token can send message to any other microprocessor. Each microprocessor stores overall data so when it gets the token it can reconfigure the whole system if necessary.
