What This Document Is
This document explores the theoretical foundations of designing and analyzing systems where data continuously flows between processing components. Specifically, it delves into “dataflow process networks,” a computational model used in the field of embedded systems. It examines how to represent concurrent processes and their interactions, offering a framework for understanding complex systems built from interconnected, independent units. The material builds upon established concepts in computation theory and applies them to the unique challenges of embedded system design.
