thanks for pointing this guy out. The first thoughts that came to my mind were:
- DSA (Digital Signal Analysis) and
- fast 'D/A converter' interpolation
I vaguely remember the first '1-bit D/A converter' inscription in a CD-player (a Sony 5-disc CD-carroussel, perhaps?) I saw in the 80´s and I wondered, at that time, that a set of 1-bit D/A converter/analyzer chips might have been introduced. Never had those thoughts anymore until now.
Would the RPN-structure enhance performance? The block-diagrams suggest it can be used as part of a fast process controller, and I can only understand output directly connected to the input when internal compensation occurs, and in this case, the 1023-word programming would find purpose if fast enough.
Based on the 80´s 'technology shift' that began to endorse fixed, fast and easily programmable/customizable hardware, I'd bet in a mid-term, well-balanced HW/SW implementation. My memory only points to the HP28 as one of the first well-know implementing of RPN-like stack through SW.
