Need to implement 16 point **FFT** in Verilog (Xillinx) , and use memory based LUT optimization , using the research paper attached to optimize the 16 point **FFT**, and compare the Area and Timing of both the optimized and un-optimized implementation.
Will need a small write-up comparing both the results , complete source code of both the implementations.

...gt(m,k:k+len-1) needs to be updated as you advance the time frame.
When you have the output of mth frequency channel, i.e., gt(m,k:k+len-1), it doesn't make sense to take its **fft**. Rather, find out the average or rms value of that frame and it will be the spectrogram value in nth time frame and mth channel. If you put together values from all frequency

The implementation will use the methods for **FFT** and IFFT provided by the Accelerate Framework, and be as optimised as possible for performance in iOS devices.
The implementation will be a single Objective-C class with a single method. This method will take as input a pointer to a float buffer and the length of the buffer.
It will return a buffer
