Data Processing Unit Using COTS Micro-controllers Working in Redundancy

Abstract

This paper presents the implementation of an new architecture based on majority voting decision. The architecture is composed by four cots at least four ARM-M4 processors operating simultaneously and communicating via CAN-bus. The proposal is that all processors runs the exact same software without using the concept of master and slave. To run in this mode, each processor has to only know its own identifier and the total number of processors in operation. In this article we present hardware and software details and preliminary results performed having in mind logical constraints.
