Square Root On A PIC
November 2006
Square roots have been in use for thousands of years in construction and astronomy. Today, they are also used for computing RMS values, FFTs, and other types of digital filtering, navigation, and more. With more and more smarts being put into smaller and smaller devices, there is greater need to run a square root function on a small, low-power MCU. Typical methods for computing square roots are slow and difficult to implement on a small MCU. They require multiply and divide functions...
