Introduction

This example performs HWA based FFT operation on real input data.

The input to the FFT is a sinusoidal real data. This is converted to 16-bit signed fixed point data which the HWA will operate on. The HWA PaRAM sets are initialized with proper configuration for FFT. The HWA is triggered to perform the FFT operation and the frequency domain complex output is converted back to 16-bit signed data.

Supported Combinations

Parameter	Value
CPU + OS	m4fss0-0 nortos

Steps to Run the Example

• When using CCS projects to build, import the CCS project for the required combination and build it using the CCS project menu (see Using SDK with CCS Projects).
• When using makefiles to build, note the required combination and build using make command (see Using SDK with Makefiles)
• Launch a CCS debug session and run the executable, see CCS Launch, Load and Run
