5.1 INTRODUCTION
Dataflow modelling describes the architecture of the entity under design without describing its components in terms of flow of data from input towards output. This style is nearest to RTL description of the circuit. Dataflow modelling is concurrent style of modelling in VHDL, that is, unlike behavioural modelling the order of statements is not important ...
