number format multiply divide in STM32H757

[vishalb1911]

Hi,

I am looking macro, in-bult function or lib to

1 - I can do 2 16-bit signed fraction number multiply or divide and result should also be in 16-bit signed fraction.

2 - define to convert any integer number (value less will be less than "1" to 16-bit) fraction number

we are working on real time data, so scaling is not working for us

In the same instruction? There isn't an instruction for that. You could make your own macro but it wouldn't be particularly fast, which seems like the goal here.
