Consider discussion to be extended Re: Motion 10: low-cost and embedded systems



Nate et al,

Consider discussion to be extended until Juergen posts a
friendly amendment and informs me voting is ready to begin.

Discussion is good!

Please forgive me if it is too late to ask this question. I know discussion period for Motion 10 ended Nov. 24; it also doesn't seem like the voting period has officially begun, either (so I'm a little confused). In any case, I don't think my question requires any change to the motion.

My question to P1788 is: how do very low-cost and/or embedded systems fit into the picture of P1788 and required functionality?

I know various methods exist to compute transcendental functions (CORDIC, polynomial approximations, etc.). I have no doubt implementations for modern CPU/GPUs can handle all the Motion 10 required functions, either in hardware, software, or a combination of both. Even my hand-held TI-89 graphing calculator supports these functions... with a full-featured Computer Algebra System to boot!

But even the TI-89 has fairly ample memory and processing power. But can anyone imagine some hypothetical low-cost or embedded microcontroller where even a software implementation of all these functions might be too much?

If such examples exist, what do we do about them? Can they still be called 1788-conforming? If yes or no, is it important?

I'm not sure what the answers are to these questions. So this is why I ask P1788 what do you all think?

Sincerely,

Nate Hayes
