Microcontroller's memory enough for a code which implements Look-up table (LUT)

Hi Abdul,

C2000 controllers are very well equipped for implementing LUT. Also, how big is it going to be, is it Sine LUT?

Hi Gautam,

Thanks you so much for your reply. It is a 3D LUT, which depending upon input picks up phase and amplitude, which produces a multi-sine signal. Is there any way way by which we can check a microcontroller will work perfectly in terms of supporting software suite before buying it.

One more thing, I see a list of software in the following link: http://www.ti.com/lsds/ti/microcontrollers_16-bit_32-bit/c2000_performance/real-time_control/tools_software.page#controlsuite. So, which software is most suitable for my application, so that I can implement my LUT code in the microcontroller?

Thank you.
Abdul

Yes, you need to download controlSuite for peripheral headers and sample codes.

Hi Gautam,

Thanks you so much for your reply. I think you forgot about this question. So, you asked what is your LUT implementation? It is a 3D LUT, which depending upon input picks up phase and amplitude, which produces a multi-sine signal.

Thank you.

Abdul,

In principle either device will do what you want. The best choice depends on how much memory is needed (i.e. how big the look-up table is) and how much the device costs. Unless you're very constrained by device cost I recommend going with the F28377D. That has much more memory and performance so you're less likely to hit a bottle-neck.

There isn't any example code which does exactly this, at least not from TI, but in principle it is straightforward. I can't comment on The Mathworks side but I'm pretty sure the tools would do a good job of generating efficient code.
