Is there any detailed documents for IPU to describe the interfaces between modules, what is the methods used to transfer data between modules, I am wonder what channels can be used to send data between DP and DC (only 23 and 28 be used?), what chanels are used to send data between IDMA and DC directly if DP is not used, and what IDMA channels are used to send data to DP only? It is really hard to configure IPU without the detailed description about the interface between these modules.
