Please take a look at the IPC training material to understand how the communication works. It should not be noted that the IPC can utilize the message RAM’s and shared RAM blocks to pass data between processors at a fixed address known to both processors. See the IPC_data_transfer section in the link below.
对的,我知道有Message RAM和GSRAM可以用但是我还是想知道他们通信的原理是什么呢?是有总线吗?还是单纯依靠RAM
据我所知,message RAM是唯一的通信方式。
