SYSBIOS benchmarking information (boot time) with TMS320DM6467

Other Parts Discussed in Thread: SYSBIOS

Hi team,

Do we have any available information regarding boot times for a DM6467 running SYS/BIOS?  Granted, I understand that this is a rather open ended question but I have a customer who is wanting to achieve cold boot times of < 1s (current consumption is a major concern when the device is not active) so they are wanting to essentially shut down after X minutes have passed of inactivity and cold boot .  Their initial interest was no operate OS-less but I advised that going without an OS of any kind would cause them to require major FW development since nearly all codecs and SDKs are OS-based.

Any kind of information that you have to offer would be greatly appreciated.

Regards,

Michael

    Michael,

    We don't have any sort of published benchmarks for boot times.  Furthermore, this is really dependent on many factors like clock rate and where in the sequence it is initialized, amount of initialized data (cinits), where stuff is placed in memory (fast or slow), number/type of xdc.runtime or SYS/BIOS modules being used.

    I will say that 1s is a lot of time and I'm quite sure that SYS/BIOS will take a lot less than 1s.

    Michael,

    We've done boot time optimization on different TI platforms and has achieved very good boot time numbers as good as 2.6 secs on Linux with applications. We could boot linux kernel with bootloader and mount the filesystem in about 700ms on DM36x. If you are interested please get in touch with us.

    Hi Renjith,
    could I have some information/documentations about SysBios overhead. I'm searching papers or benchmarks, but I didn't found anything.
    Thanks

    Hi Geni,
    We generally discourage posting a new question to an answered thread. It weakens the search feature of the forum. For this reason, I suggest you start a new thread with your question and reference this thread.

    Hi Kenia,
    ok sorry.
    I already started a new thread about it, I'm waiting there to have an answer.
    Thanks and sorry again.
