1# CMSIS-DSP {#mainpage}
2
3**CMSIS-DSP** is an open-source software library that implements common compute processing functions optimized for use on Arm Cortex-M and Cortex-A processors. The library covers such compute categories as (list not exhaustive):
4
5 - Basic mathematics (real, complex, quaternion, linear algebra, fast math functions)
6 - DSP (filtering)
7 - Transforms (FFT, MFCC, DCT)
8 - Statistics
9 - Classical ML (Support Vector Machine, Distance functions for clustering, ...)

11## Access to CMSIS-DSP
12
13CMSIS-DSP is actively maintained in a GitHub repository and is released as a standalone package in the CMSIS-Pack format.
14
15 - [**CMSIS-DSP GitHub Repo**](https://github.com/ARM-software/CMSIS-DSP) provides the full source code of CMSIS-DSP functions.
16 - [**CMSIS-DSP Documentation**](https://arm-software.github.io/CMSIS-DSP/latest/) explains how to use the library and describes the implemented functions in details.
17 - [**CMSIS-DSP Pack**](https://www.keil.arm.com/packs/cmsis-dsp-arm/versions/) delivers CMSIS-DSP components and examples in [CMSIS-Pack format](https://open-cmsis-pack.github.io/Open-CMSIS-Pack-Spec/main/html/index.html).
