TMS320F28388D: Is the on-chip Arm Cortex-M4 able to access additional off-chip memory devices?

Good afternoon,

Some applications require an amount of RAM that may exceed internal RAM capabilities. That is why we are thinking about extending this RAM through external off-chip memory devices controlled via EMIF. Is the on-chip Arm Cortex-M4 able to access additional off-chip memory devices?  

Thanks! 

EMe.

    Hi Eric,

     Is the on-chip Arm Cortex-M4 able to access additional off-chip memory devices?

    Cortex-M4 does not have access to EMIF module which has access to off-chip memory device. You need use CPU1 or CPU2 to read the data and pass through IPC to Cortex-M4.
