1/ this sound a bit problematic - if you connect 100 pins to dsp you will be left just with 8 i/o pins.
2/ basically you can use all 108 pins as i/o but 7 of them are inputs only, some have other importent usage like clock or differential capabilities.
3/you can use them by specifing there location, and usage in a UCF file, or by other means.

Thanks for the reply. I got all your points mentioned. Can you please explain me in detail regarding the DUAL type and CLOCK type I/O's available?
Dual type I/O's are 40 in number. But how can I use them after configuration as general purpose. Regarding the clock pins, how are the clock pins are selected for the design. They are 30 in no. But I don't understand how can I use those pins.
