Is there other DSP lib besides the CMSIS DSP-lib for teh CC3200?

Other Parts Discussed in Thread: CC3200

I called the CMSIS dsp-lib arm_rfft_init_q15 function in my CC3200 code. The .const segment grew from 10 KB to 215 KB.

Is this normal? Did I do something wrong?

If this is normal, I cannot use the CMSIS lib since the CC3200 only has 240 KB for both code and data.

Does anyone know if there is other alternative dsp lib which uses less code space for the CC3200?

Thank you.

I haven't used the CMSIS library myself so cannot comment with certainty about the growth of the .const section. However there might be actions you could take (such as turning on higher levels of optimization to reduce code size, redirecting allocation of different segments etc) to help alleviate some of the issues. This related thread may also be helpful.

Regarding an alternate library, the CC3200 device forum might be a better place to ask about that.
