POLYNOMIAL OPERATOR IN THE BODIES OF GALOIS AND DIGITAL SIGNAL PROCESSING PROCESSOR HAVING SUCH AN OPERATOR

摘要

P THE POLYNOMIAL OPERATOR IN THE GALOIS BODIES FOLLOWING THE INVENTION IS ORGANIZED IN THREE LEVELS: A LEVEL OF MULTIPLEXERS M0, M1 FOR SELECTING AND TRANSMITTING TO REGISTERS AT A SECOND LEVEL THE OPERANDS TO BE USED FOR THE SUCCESSIVE STEPS OF THE CALCULATION; - A SECOND LEVEL SAID "PIPE LINE" WHICH HAS THREE ROCKET REGISTERS R0, R1, R2 TO PUT IN MEMORY THE OPERANDS SELECTED AT THE FIRST LEVEL; - A THIRD LEVEL, FOR CALCULATION, WHICH HAS A MULTIPLIER-ADDITION MAG WHICH INPUTS X, Y AND Z ARE RELATED TO THE OUTPUTS OF THE REGISTERS AND PROVIDES THE COEFFICIENTS OF RESULTING POLYNOMES IN THE BODIES OF GALOIS BY ALWAYS THE SAME CALCULATION X (YZ) BY REPEATING THE SAME CONTROL DIRECTION. / P P THIS OPERATOR IS APPLICABLE IN DIGITAL TELECOMMUNICATIONS FOR THE CODING AND DECODING OF BCH OR RS (REED SOLOMON) ERROR CORRECTING CODES AND PERMITS THE REALIZATION AN INTEGRATED PROCESSOR LIKELY TO PROCESS DIGITAL DATA AS OCTETS. / P
