What is Dataflow Programming?

What is sequential programming?

Code executes in the order it is written

Dataflow programming? Code executes as soon as it has valid arguments

Highly parallel

Data Flow

Block diagram execution Dependent on the flow of data

Block diagram does NOT execute

left to right

Node executes when data is

available to ALL input terminals Nodes supply data to all output

terminals when done

If the computer running this code had

multiple processors, these two

pieces of code could runindependently without additional

coding

Polymorphism Definition: a programming

language feature that allows

values of different data types to

be handled using a uniform

interface.

In LabVIEW: the ability of VIsand functions to automatically

adapt to accept input data of

different data types

i.e. Numeric Functions

Useful when performing the sameoperation on different data types
