TMS320F28379D: GS RAM to share variables

Hi,

I can share the variables using IPC protocol also right. What is the advantage of using GS RAM over this?

    Hello Rishitha,

    The GS RAMs are configured to be either CPU1 R and CPU2 R/W or CPU1 R/W and CPU2 R as shown below. The IPC is used for doing a handshake (i.e. checking the IPC flag statuses by each CPU to make sure they start synchronized) and data transferring, where as the GS RAM allows larger data to be stored by one CPU and read from either CPU.
