I see that there are only `arm_mat_mult_f32`, `arm_mat_add_f32` functions in the source code.
Does CMSIS-DAP sup…

Hello all,
Was there some reason DSP omits ld-PI/uq-out and lq-PI/ud-out inline modules? I have checked arm_math.h and they are not included. Clarke Park transforms appear to be useless without som…

## Introduction
This is a proposal to move the CMSIS out of the main Zephyr repository.
### Problem description
CMSIS is one of the two "hal" layers that are still part of the main Zephyr tre…

Hi,
I was facing a problem in FFT calculations time (Q15), the version with ```-U__ARM_FEATURE_DSP``` was executing much faster than the version with DSP instructions enabled. For 16k samples, I go…

The code comments in the DSP library are not correct. This is a hangover from a bug in the previous versions of the DSP library (see #148 for details).
From arm_math.h:
```

I recently upgraded a project from 5.4.0 to 5.6.0 and noticed that a performance-critical algorithm got about 17% slower. I traced it down to arm_scale_f32. The difference seems to be in a change to h…

**Objective**
Link-time optimisation, or LTO for short, is the crucial feature for embedded programming. Specifically, even simple Fourier transform using CMSIS_DSP libraries can easily overflow flas…
