CCS/AMIC110: power down partly

Part Number: AMIC110

Tool/software: Code Composer Studio

Hi

Is it possible with the AMIC110 to put the two PRUs in powerdown and continue to work with the A8?

Could I also put the external DDR Ram in powerdown and only work with the A8 and its memory, if so where is such a procedure described?

best regards 
Thomas

    Hi Thomas
    Can you clarify the intent on why you want to power down the PRUs? Is it to save power? As far as I recall the PRUSS does not consume much power to begin with.
    Are you using Linux or RTOS?

    Similarly on DDR , is the intent to not use DDR at all in your design and just work with on chip memory, or you plan to use DDR and just need to put it in power down mode periodically?

    Regards

    For DDR, it all depends on if you want to maintain the contents of the DDR. If not, you can just disable the EMIF module clock. If you want to maintain the contents, you have to go through a self-refresh sequence.
