Avar isn't all that complex and fantastic. It was done ehm... in the 
80ties... (TS105A - using the whoppa-tronic 6502 for real-time 
calculations for up to 4 tau-values).

One thing which I have found very useful in instruments like HP4195A is 
a built-in language. It beats the (still very handy) math processings.

Basic, forth or Lua... as long as it is simple to edit and cook-up 
programms/apps/macros/scripts. It doesn't have to be very fast, but 
keeping up with PPS for moderate complex stuff and say 10-100 Hz for 
quicker stuff would be handy.

Cheers,
