Digital generator for pseudo - mersenne - transformation

摘要

P generator of the transformed discrete. / p & & p & this device is intended to generate the pseudo mersenne transforms ak with a series of words {year }. The words year, are introduced into a predetermined order and in series by a bit, in a circuit with recirculation sri provided with sockets. The connectors are connected to the inputs of an adder add1, belonging to the accumulation circuit series - parallel, through a set of a two-position switch sw2. These accumulations series - parallel supply of the terms "bk * * * * bk 1 and 2 which will then be added together (modulo 2 * * q - 1 (q being a first number given) and subtracted from each other (modulo 2 * * q + 1, in order to provide the terms" ak 1 and ak * * * * 2. These terms are introduced into a circuit for supplying weighted additions ak (for k not = o). / p & & p & the signal treatment. / p
