Автоматизация процедуры выбора микроконтроллера

   Currently many microcontrollers are produced around the world. They belong to different classes, thus may be used in different applications, they differ from each other in architecture and productivity of built-in-processors, peripheral set, memory volume, etc. But at the same time for the concrete task the only one microcontroller is necessary. Unfortunately, there is not "the best" microcontroller for all possible cases. Selection of the microcontroller is complex multicriteria task. The choice depends on many factors, for example the features of the task, designer's skill and preferences, required technical features of microcontroller, economical requirements and even of fashion in some sense. Precise methods for decision of such kinds of tasks are absent. The authors propose to solve the task of microprocessor choice using decision making theory in several steps. The first step is to define expert group. The group formulates criteria list as a base of future microcontroller choice, then during next steps number of choices is reduced sequentially and as result optimal in some sense microprocessor may be selected. The described approach of microcontroller choice may be automated.
