 [ARM](https://www.arm.com/) stands for Advanced RISC Machine, which is a collection of reduced instruction set computing architectures for CPUs configured for various development environments such servers, IoT, and other mobile devices. Arm was acquired by [NVIDIA](http://www.nvidia.com/page/home.html) in [September 2020](https://www.arm.com/company/news/2020/09/nvidia-to-acquire-arm).
 
+[Digital signal processing (DSP)](https://developer.arm.com/architectures/instruction-sets/dsp-extensions) is the use of digital processing, with computers or specialized digital signal processors, to perform a wide variety of signal processing operations.

+[Floating-point](https://developer.arm.com/architectures/instruction-sets/floating-point) is a variable type that is used to store floating-point number values. A floating-point number is one where the position of the decimal point can "float" rather than being in a fixed position within a number. Floating-point is particularly suitable when computational accuracy is a critical requirement and is essential for a wide range of digital signal processing (DSP) applications. Many applications that involve large data sets or data sets with unpredictable ranges also benefit from the precision and dynamic range of floating-point data types.
