Date Oct. 10, 1996Method of signal processing application graphical entry with the aid of a digital computer. The method starts from data structured into tables displayed in the form of Cartesian grids (X, Y, Z, T) by implementing at least one transformation on these data (F), in that a set of elementary transformations is available in library, in that for each transformation, at least one operand application table is compiled at input and at least one result application table is compiled at output, in that an operand array is compiled at input to each elementary transformation and a result array is compiled at output, and in that for each Cartesian coordinate axis, at least two elements of the operand array and of the operand application table on the one hand, of the result array and of the result application table on the other hand are matched up, and in that the affine relations characteristic of the accesses to the tables for signal processing are used to compile, per iteration, with the aid of software included in the graphics tool, on the basis of at least two matches, all of the accesses necessary for the complete execution of the relevant transformation.
