Abstract:
The FFT processor is a critical block in all multicarrier
systems used primarily in the mobile systems
for image and digital signal processing applications.
It is therefore interesting to develop an FFT
processor as a widely usable VLSI building block.
In order to be flexible so that the processor can be
used in a variety of applications without major
redesign , the performance in terms of computational
throughput , and transform length should be: easily
modifiable. This system implements the 16 point
radix 4 parallel Fast Fourier Transform processor
with sfixed format (signed fixed point representation)
and focuses on the complex multiplier design with
two different approaches.
