1. dsp和arm通过配置ipc中断寄存器进行通信。
程序路径：
/home/lr/workspace_v6_0/ARM_DSP/ARM_DSP_Communication_ARM
/home/lr/workspace_v6_0/ARM_DSP/ARM_DSP_Communication_DSP
程序输出：
[C66xx_0] Initialize DSP main clock = 122.88MHz/4x39 = 1198MHz
Waiting for interrupt from ARM Core0!
[CortexA15_1] Interrupt init success
Trigger the IPCGR0 to generate the interrupt to DSP Core0!
Waiting for interrupt from DSP Core0!
[C66xx_0] Received interrupt from ARM Core0!
Trigger the IPCGR8 to generate the interrupt to ARM Core0!
结论和问题：DSP可以接收到ARM发出的中断。ARM不能接收DSP发出的中断。
2.dsp核间通过Transportshm进行通信。

结论和问题:
必须使用版本号为03.0 1 .0 2 .0 5的mcsdk提供的image才能完成通信。使用3_01_03_06和3_01_04_07版本的会出现arm端不能接受到dsp端发送过来的MessageQ信息。
4、arm核间使用TransportQmss进行通信。
