Calculator buttons using flip-flips to store numbers as binary?

Click For Summary

Discussion Overview

The discussion centers around the feasibility of using flip-flops to store numbers in binary for a calculator-like application. Participants explore the concept of inputting digits and how they could be represented using flip-flops, particularly in the context of digital electronics and microprocessor design.

Discussion Character

  • Exploratory, Technical explanation, Conceptual clarification

Main Points Raised

  • One participant inquires about the possibility of using flip-flops to store binary representations of numbers inputted into a calculator, specifically mentioning the example of the number 5 being stored as 0101.
  • Another participant asserts that using flip-flops in this manner is indeed how it is done, though no further details are provided.
  • A different participant expresses a desire to implement a system where pressing buttons 0 to 9 would result in storing 4 bits in four NAND flip-flops.
  • One participant questions the clarity of the initial proposal, suggesting that the goal may be to design a simple microprocessor and recommends consulting a digital electronics textbook for further understanding.

Areas of Agreement / Disagreement

There is no clear consensus among participants. While one participant affirms the feasibility of the proposed idea, others express uncertainty about the overall goal and clarity of the design.

Contextual Notes

Some assumptions about the design and functionality of the proposed system remain unaddressed, and the discussion does not resolve the specifics of how the flip-flops would be implemented in practice.

Is it possible to use flip-flips to store numbers inputted, for example if i input 5, current will go to 4x nand flip flip and store 0101 and the next digit to be calculated, any ideas on this?

That is how it is done.
 
I want to use it like a calculator, when you press 0 to 9 button 4 bits will be stored in 4x nand flipflops
 
What you want to make is not clear. I guess you want to design a simple microprocessor. In that case read a digital elec book like mano.
