The IPC module is a 32 Byte wide Scratch Pad that connects together PRUn and RTU_PRUn (where n = 0 or 1) cores within a Slice. Figure 6-207 represents the mapping between IPC Scratch Pad (IPC SPAD), PRUn and RTU_PRUn cores..
The firmware needs to define which bytes are owned by each of the PRUn/RTU_PRUn cores. There is no hardware arbitration.
