Abstract:
1. An information processing device comprising: a first terminal capable of coupling with a baseband processing portion; a second terminal capable of coupling with an audio processing portion; a first serial interface capable of exchanging compressed data with the baseband processing portion coupled through the first terminal; a speech processing portion capable of processing a speech signal incorporated by the first serial interface; a clock generator that generates a clock signal for PCM communication; and a second serial interface that uses a clock signal generated from the clock generator to enable PCM communication between the audio processing portion coupled through the second terminal and the speech processing portion, wherein the first serial interface includes a notification signal generation circuit that generates a notification signal each time compressed data incorporated from the baseband processing portion reaches a predetermined data quantity, and notifies the speech processing portion of this state using the notification signal, wherein the speech processing portion includes a synchronizing signal generation circuit that generates a network synchronizing signal based on the notification signal, and wherein the clock generator generates the clock signal for PCM communication based on the network synchronizing signal generated from the synchronizing signal generation circuit.
