Polynomial operator in the galois fields and signal processing processor, 1984, comprising such an operator

摘要

The polynomial operator in the galois bodies according to the invention is organized into three levels: - a level of the multiplexers m0, m1 to to select and transmit to the registers of a second level the operands to be used for the successive steps of the calculation; - a second level of the so-called "pipe line" flip-flops, which comprises three registers r0, r1, r2 to be placed in memory the operands selected the first level; - a third level, for the calculation, which includes a multiplier - add mag whose entrees x, y and z are connected to the outputs of registers and which provides the coefficients of the polynomials insulation in the galois fields in which is always the same calculation x (y, z), by repetition of the same control instruction. / p & & p & this operator is applicable in the telecommunications] for the coding and brief of error correcting codes bch or rs (reed solomon) and allows the embodiment of a processor integrated capable of processing data] in the form of bytes.
