Thanks for your reply.
My application changed a little, now I am not interfacing the display unit but using PC to analyze the data. I thought usage of OMAP series of T Instrument would be waste of money as it has developed for Video Processing Application..
I went through Atmel Diopsis DCP+MCU unit and found it quite useful, please find the link below

I think DSP clock which is 100 MHz, is quite much to perform 2048 point FFT or even more, what do you say ?
One difficulty I am encountering is that, I couldn't figure out the actual RAM and ROM momory of the device, some time it shows 370 KB SRAM memory of DSP unit but inside datasheet written this way..
1.7 Mbits of On-chip SRAM:
– 16 K x 40-bit Data Memory Locations (6 Memory Accesses per Cycle)
– 8 K x 128-bit Dual Port Program Memory Location, Equivalent to ~50K DSP
Can you please help me out with memory issue ? Also, will it be possible to do anti aliasing filtering befor doing FFT calculation using this device ?
I will appreciate your help.
