Method for generating piecewise-affine multivariable functions with on-line computation of the search tree and device for implementing same

Abstract

[ES] Método para generar funciones multivariables afines a tramos, en donde se realiza la computación on-line del árbol de búsqueda para la localización del valor de entrada en los politopos de la partición, y la posterior generación d ela correspondiente función afin. Asimismo se propone un dispositivo configurable y programable para generar funciones multivariables afines a tramos compuestos por una arquitectura con cuatro bloques funcionales siendo éstos: un bloque unidad de control (1), un bloque de memoria árbol, un bloque de memoria de parámetros y un bloque de unidad aritmética; y presenta al menos tres modos de operación seleccionables mediante distintos valores de un bus (config): escritura de la memoria del árbol, escritura de la memoria de parámetros y evaluación de la función afin. Puede incluir un cuarto modo de operación, que es el modo de test.

[EN] The invention relates to a method for generating piecewise-affine multivariable functions, comprising the on-line computation of the search tree in order to locate the input value in the polytopes of the partition, and the subsequent generation of the corresponding affine function. The invention also relates to a configurable and programmable device for generating piecewise-affine multivariable functions, formed by an architecture having four functional blocks, namely a control unit block (1), a tree memory block, a parameter memory block and an arithmetic unit block, as well as having at least three operating modes that can be selected using different values of a bus (config): writing of the tree memory, writing of the parameter memory and evaluating the affine function. The device can also have a fourth operating mode, i.e. the test mode.
