IMPLEMENTATION OF AN ALGORITHM FOR SQUARE ROOT COMPUTATION IN AN FPGA ARRAY BY USING FIXED POINT REPRESENTATION

Abstract

En este trabajo se presenta la implementación de la raíz cuadrada de un número en un dispositivo FPGA. El algoritmo usado no es un algoritmo de convergencia, por tanto, la exactitud del cálculo es muy alta, además no existen restricciones de ningún tipo para que la operación sea llevada a cabo. El uso de hardware en la FPGA es mucho menor que el usado por otros algoritmos que también calculan la raíz cuadrada de un número. Para representar el número se usa la representación de punto fijo, para ello se usan dos parámetros, N y M, donde N define el número de bits que representan la parte entera y M define el número de bits de la parte fraccional. M y N son definidos en la síntesis del módulo.
