Is there any provision for Implementation of Hot-Swappable redundancy in a DSP Processor ??

    Hi Komal,

    Could you give more detailed description about your issue and what you want to do?

    Sir,

    In case an my DSP Processor fails at any point. Is there any possibility that a similar DSP processor serves to be a back up for my system and the system continues to function without fail.

    Hi Komal,

    Your requirements are still unclear.
    1. I could envision two separate identical PCB systems isolated from each other - one as a backup.
    2. Or if you need to replace a DSP on a board easily, you could reflow a new DSP or use a socket... All volatile memory inside the DSP and off-chip RAM will be lost when power is removed, but external flash can be used to preserve some system status. What is the scenario?

    The Hercules Safety MCU may be of interest to you.
    www.ti.com/.../overview.html

    The two ARM Cortex-R-based MCUs (80MHz up to 330MHz) can operate in LockStep (1oo1D safety concept). They support fixed- and floating-point options, 1.66 DMIPS/MHz..

    Regards,
    Mark

    Yes sir, both the approaches seems meaningful. Could you please throw some light on what are the key parameters that should be considered for both of the above mentioned solutions...like in 1.) Can you give a block diagram view of how the connections could be made and is there a need for any specific controller to maintain the link between the two DSPs..?
