The reconfigurable platform consists of integrated circuits whose internal connections can be programmed by the user. Automatic reconfiguration may potentially be driven by Evolutionary Computation techniques such as Genetic Algorithms to synthesize complex circuits. Field Programmable Gate Arrays (FPGAs) and Field Programmable Analog Arrays (FPAAs) constitute the state of the art in the technology of reconfigurable chips, referring to digital and analog devices respectively. These devices will become the building blocks of a forthcoming class of hardware, that will encompass important features of self-adaptation and self-repairing through automatic reconfiguration. These are essential features for systems that need to perform for a long time in harsh environments such as those employed in space exploration missions. In this paper, the reconfigurable platform architectural details, concept and some preliminary tests are presented

The EHW analog platform, named PAMA (Programmable Analog Multiplexer Array), is a reconfigurable platform that consists of integrated circuits whose internal connections can be programmed by Evolutionary Computation techniques, such as Genetic Algorithms, to synthesize circuits. The PAMA is classified as Field Programmable Analog Array (FPAA). FPAAs have just recently appeared, and most projects are being carried out in universities and research centers. They constitute the state of the art in the technology of reconfigurable platforms. These devices will become the building blocks of a forthcoming class of hardware, with the important features of self-adaptation and self-repairing, through automatic reconfiguration. The PAMA platform architectural details, concepts and characteristics are discussed. Three case studies, with promising results, are described: an operational amplifier, a logarithmic amplifier and a membership function circuit of a fuzzy logic controller.
