OMAP-L138: 请问ARM+DSP之间裸机操作可以通信吗？

user4583488 说：

如果双核都进行裸机操作，那么两者之间还可以用SYSLINK进行数据交换吗？还说两者之间通信必须得用操作系统

SYSLINK比较老了支持有限，目前的SDK中都是使用IPC。

IPC 3.x merges the IPC 1.x and SysLink 2.x products, creating a single product that defines multiprocessor communication APIs and provides implementations for several OS's, including SYS/BIOS and HLOS's.

The SysLink name is being retired. The SysLink 2.x product will continue to be supported on existing devices, but development has stopped and support for new devices will not be added.

ARM核，DSP核两者可以并行操作吗？各干各的，DSP只顾着处理数据，ARM忙着进行数据显示或者逻辑控制。

可以。
