Hi All,

I came across someone sharing these two papers about fast INVT_SQRT
innovations just now. I'm not sure if they are relevant to us as it
seems they are focussed on the software side (using fmac) not the
hardware side but I could have misinterpreted. Are these worth adding
to the resources page?

Fast Calculation of Cube and Inverse Cube Roots Using a Magic
Constant and Its Implementation on Microcontrollers

Modified Fast Inverse Square Root and Square Root
Approximation Algorithms: The Method of Switching
Magic Constants
