Abstract
Se proporciona un dispositivo de cómputo, configurado para calcular una función de una o más entradas, el dispositivo comprende un dispositivo de almacenamiento que almacena una o más tablas de consulta utilizadas en el cálculo de la función, las tablas de consulta asignan valores de entrada a valores de salida, la tabla de consulta está construida con respecto al primer código de corrección de error, un segundo código de corrección de error, un primer umbral de error y un segundo umbral de error, de tal manera que cualquiera de dos valores de entrada (112) en los que cada uno difiere cuando mucho en un número de bits del primer umbral de error de una misma palabra de código del primer código de corrección de error, son asignados a valores de salida respectivos (131-38) en los que cada uno difiere cuando mucho en un número de bits del segundo umbral de error de una misma palabra de código del segundo código de corrección de error, en donde el primer umbral de error es por lo menos 1 y cuando mucho la capacidad de corrección de error (t1) del primer código de corrección de error, y el segundo umbral de error 10 es cuando mucho la capacidad de corrección de error (t2) del segundo código de corrección de error.
