Discussion Overview

The discussion revolves around the potential speed and efficiency benefits of analogue processors compared to binary processors, particularly in the context of processing information with varying states, such as decimal bits or bits with 100 states. The scope includes theoretical considerations and implementation challenges.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation

Main Points Raised

  • One participant questions whether analogue processors could provide significant speed improvements over binary processors, especially when considering bits with multiple states.
  • Another participant highlights the complexities involved in representing multiple states, suggesting that using different voltage levels could complicate the process due to the need for larger voltage swings and longer charge times.
  • A different viewpoint suggests that the concept resembles existing technologies like ADCs to FPGAs or DACs, indicating that some aspects of analogue processing are already utilized in digital systems.
  • One participant clarifies that their inquiry is theoretical, focusing on a direct comparison between a binary machine and a decimal machine, questioning the potential for speed improvements.
  • Another participant expresses skepticism about the possibility of significant speed improvements, stating that the answer depends heavily on implementation details.

Areas of Agreement / Disagreement

Participants express differing views on the feasibility and potential benefits of analogue processing compared to binary processing. There is no consensus on whether significant speed improvements can be achieved, and the discussion remains unresolved.

Contextual Notes

The discussion highlights limitations related to the representation of multiple states and the implications of implementation choices on performance. Specific assumptions about the nature of the processing and the definitions of speed and efficiency are not fully explored.

Would a analogue processor offer significant speed ups on binary processors, on the scales of decimal bits and then if we had a bit with 100 states. I know that for the transfer of information would receive significant improvements but would this also be true for processing information?

The devil is in the details. How do you represent the 100 states? If it is by having 100 different voltage levels then you would need to have a larger voltage swing in order to differentiate between the values. This means more time to charge the caps and more time to decode what value you actually have... etc.

Not so easy when one looks at the details.
 
sounds like a adc to fpga(or other type of gate array) to dac or in other words an asic dsp, they already are analog in a way.
 
Hehehe, my idea is not using voltages. I'm not that silly. I was asking on a purely theoretical basis of having 2 machines that are the same except one works on a binary bit and the other with a decimal bit. Would we have a significant speed up?
 
Would we have a significant speed up?

It is impossible to answer this question without discussing the implementation,but in any case I can imagine the answer is no.
