STM32L4 DSP Instructions

I am new to Cortex M4 based STM32L4 series MCU. I got to know that Cortex M4 supports FPU and DSP instructions. I want to use both of them in my project.

Currently I am working with STM32L4 Discovery Kit and Keil uVision 5. To enable support of Floating Point Operation I need to select the Floating Point Hardware from the 'Target' tab of Project Options. But I don't know how to enable/use the DSP instructions. Do I need to enable it explicitly?

I need to perform FFT using this MCU and DSP Instructions will help to improve the performance for the same. Can someone please help me on this?
