Abstract

SE DESCRIBE UN METODO PARA PLANIFICAR LA EJECUCION DE LOS PROCEDIMIENTOS DE TRANSMISION-RECEPCION POR MEDIO DE UN SENCILLO PROCESADOR EN UN DISPOSITIVO MODULADOR-DEMODULADOR TIPO FULL-DUPLEX. SE EMPLEAN MEMORIAS INTERMEDIAS JUNTO CON EL MICROPROCESADOR PARA GARANTIZAR LA AUSENCIA DE ERRORES EN LOS PROCEDIMIENTOS DE PROCESO DE LA SEÑAL. EN LA MATERIALIZACION DEL METODO, LOS PROCEDIMIENTOS DE TRANSMISION SON PRIORITARIOS, DE TAL MANERA QUE SI UNA POSIBLE SEÑAL SE TRANSMITE, SE EJECUTARA POR EL PROCESADOR UN PROCEDIMIENTO DE RECEPCION DE FORMA QUE INTERRUMPE LA TRANSMISION DE LA SIGUIENTE SEÑAL. ESTA PRIORIDAD ES MUY UTIL PORQUE LOS PROCEDIMIENTOS DE TRANSMISION SE REALIZAN MAS RAPIDAMENTE QUE LOS DE RECEPCION.
