QN9080: functions from arm_math executed in Cortex core or FSP ?

[yorick_brunet]

Hello,

I currently have a system with two microcontrollers. One handles BLE and the other handles the signal processing. I am looking for a new microcontroller that can do both.

The QN9080SIP seems to be a good candidate. However, I don't know the signal processing world. I thus have a few questions.

In the software, there are calls to:

- arm_fir_init_f32(): from UM11023 page 214/224, I assume that the FSP is able to execute a FIR up to 16 taps. The code could thus be ported to the FSP.

- arm_sub_f32(), arm_mean_f32(), arm_std_f32(): I have seen nothing in UM11023 that said that the FSP would be able to execute these instructions. These instructions would thus be executed in the Cortex-M4F core.

Am I right ?

Thank you.

Best regards,

Yorick

Hello,

Which software are you checking ? Yes, the Qn9080 will be able to execute those functions due to its core. Maybe this application note will be helpful for you as it explains a little more about the FSP and provides an example application.

Hope it helps.
