METHOD FOR GENERATING PIECEWISE-AFFINE MULTIVARIABLE FUNCTIONS WITH ON-LINE COMPUTATION OF THE SEARCH TREE AND DEVICE FOR IMPLEMENTING SAME

摘要

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.
