Procedures perform sequential computations and return values in global objects or by storing values into formal parameters. Functions perform sequential computations and return a value as the value of the function.

The dataflow representation describes how data moves through the system. This is typically VHDL allows the specification of new functions for existing operators this is called operator overloading. The parameters of the function are by definition inputs and thus do not need to have the mode (direction) specified in the function declaration.
