2142880 9501675 PCTABS00035 A radio receiver (40) for receiving an RF signal comprises receiving circuitry (42) for receiving and demodulating the RF signal and a microcomputer (44) coupled to the receiving circuitry (42) for enabling and disabling the receiving circuitry (42) at predetermined times. The radio receiver (40) further comprises an expansion chip (68) coupled to and controlled by the microcomputer (44) for communicating therewith to further process the RF signal. Communication between the microcomputer (44) and the expansion chip (68) occurs at a first speed when the receiving circuitry (42) is enabled and at a second speed faster than the first speed when the receiving circuitry (42) is disabled.
Récepteur radio (40) de signaux HF comprenant un circuit (42) de réception/démodulation desdits signaux et un micro-ordinateur (44) couplé au circuit de réception (42) pour l'activer ou le désactiver pendant des périodes prédéterminées. Le récepteur (40) comporte en outre une puce d'extension (68) couplée au micro-ordinateur (44), contrôlée par lui, et assurant un traitement supplémentaire du signal HF. Les communications entre le micro-ordinateur (44) et la puce (68) se font à une première vitesse, lorsque le circuit de réception (42) est activé et à une seconde vitesse, plus élevée, lorsqu'il (42) est désactivé.
