Abstract

Eine Sende-Empfangs-Einrichtung für Mobilfunkanwendungen weist einen Mikroprozessor (DSP), mindestens einen aufgabenspezifischen Prozessor (P1, P2, P3) und ein Prozessor-Interface (2) auf. Der aufgabenspezifische Prozessor (P1, P2, P3) ist durch Übermittlung geeigneter Konfigurationsbefehle vom Mikroprozessor über das Prozessor-Interface (2) konfigurierbar, derart, dass eine Steuerung einer von dem aufgabenspezifischen Prozessor (P1, P2, P3) ausgeführten Grundfunktion durch Ändern von Konfigurations-Parametern möglich ist.
