    • A processing load of a high performance application processing such as a voice, an image and the like is reduced, and a processing capacity of a base band processing is improved. A semiconductor integrated circuit device used in a mobile communication system such as a cellular phone is provided with a base band CPU block performing a base band processing for executing a base band protocol stack, an application system CPU block executing a high-level OS and controlling applications other than the base band processing, an application real-time CPU block executing a real-time OS and the like and controlling an image/voice processing, all of which are formed on one semiconductor chip. Further, internal high-speed buses to which these CPU blocks are connected are respectively connected via bridges.
    • 降低诸如语音,图像等的高性能应用处理的处理负担,并提高基带处理的处理能力。 在诸如蜂窝电话的移动通信系统中使用的半导体集成电路装置设置有执行基带协议栈的基带处理的基带CPU块,执行高级OS的应用系统CPU块和控制 除了基带处理之外的应用,执行实时OS等的应用实时CPU块和控制图像/语音处理,所有这些都形成在一个半导体芯片上。 此外,连接这些CPU块的内部高速总线分别通过桥连接。
