Why do you talk about subroutines when all analog?
I have been a computer programmer for years and what I have found is that if you see the functionality of a circuit as a task unto itself - I consider it a subroutine that can be accessed to generate the response needed by the calling circuit which is the core signal handler. It is important to keep in mind this is pure analog that can act so quickly it is "near" digital". This concept stems from the smallest trigger event being able to shift the velocity by parts per billion (nano-degrees).This matches the detection levels reported by the velocity detectors which use quantum physics to generate extremely high gains.
The support template surrounding the core circuit has many power supplies. Each subroutine has its own supply to maintain purity.
