TMS320F28377D: 双核之间的通讯问题

是的，内部通信主要通过IPC模块。然后因为IPC其实是在两个shared message RAMs中的，所以访问速度很快，基本可以跟内部ram访问速度类似。

官方提供的例程意思的话可以看一下每个例程main.c文件开头的注释，里面有说明工程的目的、需要观测的变量、需要的外部连接等等信息，比如第一个：

工程的目的：

//! This example tests all of the basic read/write CPU01 to CPU02 IPC Driver
//! functions available in F2837xD_Ipc_Driver.c.
//! The CPU01 project sends commands to the CPU02 project, which then processes
//! the commands.
//! The CPU02 project responds to the commands sent from the CPU01 project.
//! Note that IPC INT0 and IPC INT1 are used for this example to process IPC
//! commands.
//!

观测的变量
//! \b Watch \b Variables \b for \b CPU01 : \n
//! - ErrorCount - Counts # of errors
//! - pusCPU01BufferPt - Stores 256 16-bit words block to write to CPU02
//! - pusCPU02BufferPt - Points to beginning of 256 word block received
//! back from CPU02
//! - usWWord16 - 16-bit word to write to CPU02
//! - ulWWord32 - 32-bit word to write to CPU02
//! - usRWord16 - 16-bit word to read from CPU02
//! - ulRWord32 - 32-bit word to read from CPU02
//!
//! \b Watch \b Variables \b for \b CPU02 : \n
//! - ErrorFlag - Indicates an unrecognized command was sent from
//! CPU01 to CPU02.

无外部连接需要。
