Simple signal processing with python function call?

I like to call an external programmed python function inside of GRC
decoding a slow byte stream.

Therefore I made a simple experiment:


Signalsource with samp_rate 3200
Throttle 3200
VariableSink V2
Variable Text BOX V2 (showing the values) (decimationrate=1)

Constant source V2 * 3
Scope Sink

I planed to exchange the “V2 * 3” to an external python function to

obtain a simple signal processing routine in python

The update rate of the constant source is very slow.

Is there any better way to get a simple python extension for signal
processing in GRC?
What else can be done for higher update rate of the variable in GRC?
