阅读说明：本技术 多处理器音频系统中的无缝音频切换 (Seamless audio switching in a multi-processor audio system ) 是由 G·多乔 T·格林 M·尼默勒 于 2020-03-05 设计创作，主要内容包括：本发明涉及一种用于车辆(2)的音频系统的处理单元(1)。该处理单元(1)包括第一处理节点(10)、第二处理节点(20)和程序存储器(30),该程序存储器(30)被设计为由该第一处理节点(10)和该第二处理节点(20)覆写。该处理单元(1)被设计为使得在该处理单元(1)已经启动之后,该第一处理节点(10)计算音频输出并将其写入该程序存储器(30)。该处理单元(1)还被设计为当该第一处理节点(10)已经覆写该程序存储器(30)直到预定义点时以及当该第二处理节点(20)可操作时执行该音频输出的计算从该第一处理节点(10)到该第二处理节点(20)的切换。该第二处理节点(20)被设计为在该切换之后计算该音频输出,并将该音频输出写入该程序存储器(30)。(The invention relates to a processing unit (1) for an audio system of a vehicle (2). The processing unit (1) comprises a first processing node (10), a second processing node (20) and a program memory (30), the program memory (30) being designed to be overwritten by the first processing node (10) and the second processing node (20). The processing unit (1) is designed such that after the processing unit (1) has been started up, the first processing node (10) calculates an audio output and writes it to the program memory (30). The processing unit (1) is further designed to perform a switch of the calculation of the audio output from the first processing node (10) to the second processing node (20) when the first processing node (10) has overwritten the program memory (30) up to a predefined point and when the second processing node (20) is operational. The second processing node (20) is designed to calculate the audio output after the switching and to write the audio output to the program memory (30).)
