The Object-Oriented Protocol for Data Exchange and Control in Computational-Diverse Embedded Systems

Abstract

One of the key functionality of embedded-computer systems is control and data exchange among its building modules. Different size terminal sensors, microprocessor sub-systems, specialized devices, etc. should be able to smoothly exchange data and control notifications. This is often a difficult and time consuming task for a designer, mostly due to diversity of components. Usually the protocols and their realizations have to be implemented separately for each specific case. Therefore it would be desirable to have a definition of a protocol for data exchange and control that fits a certain class of such systems. In this paper we propose a solution to this problem which can be easily applied to different computer platforms. We start with the definition of the proposed DXC protocol. Then we present its object-oriented implementation. This way our proposition can be re-used on different platforms. The presented solution was employed with success to the suite of embedded systems for communication measurements and showed robustness and flexibility.
