Abstract

SISTEMA SINCRONO DE ALEATORIZACION DE DATOS EN PARALELO. DEL TIPO DE LOS FORMADOS POR UN GENERADOR DE CODIGOS SEUDOALEATORIOS Y POR UN BLOQUE DE SINCRONIZACION Y DE ALEATORIZACION EN PARALELO QUE ADEMAS DE LA SEÑAL DE INICIALIZACION RECIBE COMO ENTRADAS EL CONJUNTO DE DATOS DE ENTRADA EN PARALELO Y LOS CODIGOS GENERADOS POR EL GENERADOR DE CODIGOS, Y PRODUCE A SU SALIDA LOS DATOS ALEATORIZADOS EN PARALELO. LOS SUMADORES MODULO-2 UTILIZADOS EN LOS BUCLES DE REALIMENTACION DEL GENERADOR DE CODIGOS SEUDOALEATORIOS SOLO RECIBEN DOS ENTRADAS, Y LAS SALIDAS DEL GENERADOR DE CODIGOS EN LOS PERIODOS DE RELOJ DE FUNCIONAMIENTO EN PARALELO TP Y TP + 1 ESTAN RELACIONADAS MEDIANTE LA EXPRESION. CTP+1 = TN(N X N).CTP Y SIMPLIFICANDO EL RESULTADO ADECUADAMENTE. *FIG.*
