Abstract: A method for determining the position of one of two components in relative motion with respect to each other, using optical means, comprises: directing at least one light beam emitted by a light source attached to one component towards a diffractive support attached to the second component, calculated and manufactured for generating an optical signal indicative of the positioning of said support, the optical signal being produced by the diffractive support in transmission and/or in reflection, and the optical signal including information indicative of its quality; detecting and reading at least one optical code formed by said signal, which corresponds to a unique position of the diffractive support relatively to the beam; and assigning a position to each detected optical code.

Abstract: A data processor executes a table look-up and interpolate instruction which retrieves two adjacent table values from memory, interpolates between them and stores the result in a register. The same register contains, prior to the execution of the instruction, a value which is used both in calculating the address in memory from which the values are obtained and in performing the interpolation calculation. A major variant of the instruction involves obtaining the values to be interpolated between from registers, rather than from a table in memory. The combination of the two facilitates the performance of three-dimensional, or surface interpolations. It is also possible to select whether rounding is performed during the interpolation.
