Abstract

EN UNA CONEXION DE TRANSFORMACION PARA UNA INSTALACION PARA LA CODIFICACION Y DESCODIFICACION DE SEÑALES DE VIDEO EN LA QUE SE EFECTUA UNA TRANSFORMACION EN BLOQUE, PRINCIPALMENTE UNA TRANSFORMACION DISCRETA COXINUS CON AYUDA DE UNA MULTIPLICACION DOBLE MATRIX, ESTAN DCOLOCADOS VARIOS PROCESADORES DIGITALES DE SEÑALES PARALELAMENTE; EN CADA ALIMENTADOR DE PROGRAMA DE LOS PROCESADORES DIGITALES DE SEÑALES ESTA ARCHIVADO UNA MATRIX DE TRANSFORMACION; DESDE UN PRIMER ALIMENTADOR INTERMEDIO SON INTRODUCIDAS CADA UNO EN UN BLOQUE LAS SEÑALES CORRESPONDIENTES A CADA PROCESADOR DE SEÑALES; SEÑALES DE SALIDA DE LOS PROCESADORES DIGITALES DE SEÑALES SON CERTIFICADOS EN UN SEGUNDO ALIMENTADOR INTERMEDIO COMUN.
