Abstract

Die Erfindung bezieht sich auf eine Kommunikationseinheit mit einem Signalmodulator/-demodulator (220) zum Ausführen von drahtlosen oder Hochfrequenzkommunikationsvorgängen und einem Applikationsprozessor (210) mit einer Zentralprozessoreinheit sowie auf ein zugehöriges Speicherzugriffsverfahren. DOLLAR A Erfindungsgemäß sind dem Signalmodulator/-demodulator und dem Applikationsprozessor ein gemeinsam genutzter Speicher (240) und/oder eine Schnittstellenverbindung zugeordnet, wobei auf Daten des Speichers vom Signalmodulator/-demodulator und vom Applikationsprozessor zugegriffen werden kann. Der Applikationsprozessor und der Signalmodulator/-demodulator und gegebenenfalls der gemeinsam genutzte Speicher können von einem gemeinsamen Takt getaktet sein, wobei Signale vom Applikationsprozessor an ersten und Signale vom Signalmodulator/-demodulator an zweiten Übergangsflanken des gemeinsamen Taktes getaktet werden. DOLLAR A Verwendung z. B. für mobile Kommunikationseinheiten, wie Mobiltelefone und PDAs.
