Time delay / Clock cycles for C-lang Instructions - TMS470R1B1M

Geeta,

Please be aware that the TMS470R1x series (tms470r1b1m) is not recommended for new designs.  Please see the full 'NRDN' notice here.

Soon TI will be launching the new TMS470M series of microcontrollers.  This series will feature greater ARM CPU performance and a similar peripherial set to the TMS470R1 Series of microcontrollers.  Please come back soon for more information about the TMS470M Series of microcontrollers.  The product preview for the first two microcontrollers in the TMS470M series is available here: TMS470MF0660x - SPNS157. The TMS470M Series Technical Reference Manual is available here: TMS470M TRM.

Best Regards,

Hi Jean,

This is actually an old product and not new development. Therefore I need support on this particular series of microcontroller itself. Can you please give me the information regarding my query wrt instruction times (from my previous post).

Thanks

Geeta

Geeta,

In your original post you said that the device is running at 60Mhz. This is ~17 ns clock cycle.
You are trying to generate a 5ns delay by software.

This is impossible to achieve by hardware or by software.
Can you confirm the 5ns delay?

Thanks and Regards,

Hi Jean,

That is right. I am looking at alternatives for small delays ( not using timers) trying to get the size of instructions like 'for' loop etc. For example:

For(i=0; i<100; i++)

{

//do nothing ;

}

I do realise that I cannot get that small delays with the clock that I am using but looking to see what delays different instructions will give me. Is there any documentation for this?

Thank You for your earlier prompt replies.

Geeta

Hi Jean,

I am still waiting to hear from you regarding my query for clock cycle times for instructions.

Thanks

Geeta
