在MT6589中出现了Modem ARM9 是什么作用?Modem的 CPU不是ARM® Cortex-R4 processor with maximum 480MHz operation frequency?
如：In MT6589, the DRAM controller connects three systEMS via six AXI ports and supports connecting two rank DRAM devices at the same time. For cortex A7 system, we provide a 128-bit AXI port for the connection. For the multimedia system, we provide two 128-bit AXI ports for the connection. Besides, we provide three 64-bit AXI ports for connecting to modem MCU, modem ARM9 and 2G/3G. In the DRAM controller, the APB interface is for prograMMIng registers. Then we can initialize DRAM or other parameter settings.

MT6595中也出现了arm7 是什么功能呢 ?datasheet中同样没提到
求高手赐教

恩? 我的图呢
看样子modem或者协处理相关的吧，lte以后modem也会更加复杂。
莫有更详细的解释了吗 谢谢！
