Conquer the Divide - Faster Integer Division

Conquer the Divide - Faster Integer Division

Introduction

How to implement C-style integer division on a microcontroller that doesn't provide appropriate instructions? In school we learn how to divide long nunmbers [1]. Wikipedia tells us that we can do better in certain cases [2]. However, these algorithm are only better for numbers longer than a certain limit. For C operations they don't give any advantage. This article presents an algorithm based on piecewise polynomial approximation to implement this operation.

I'm building a phoenix hexapod with MG996R servos, Arduino and Lynxmotion SSC-32U controller. (At one point I tried using another 32-channel controller, but decided to go with one that's officially suppored by Phoenix code.)
