DSP Board Development

[Bagchi]

If I start developing my own DSP board with a New DSP Chip(not selected yet). What are the things I should consider? What are the detail I should require?

It depends a lot on what you would like to achieve.
Are you doing it real time, what frequency do you plan to go to etc.
Things to consider are:
Obviously speed
RAM available. Some DSP chips don't have enough
Special DSP functions such as bit reverse etc.
A2D and D2A on board

hardware support for FFT, DFT, FIR filters, etc
libraries of DSP functions available
do you need hardware floating point??

Keep in mind the availability of various package formats for the DSPs you are currently considering.

Many of the more advanced DSPs are only available in package format difficult for many individuals to incorporate into designs, such as BGA packages.

What for package formats can you effectively design and assembly a PCB?

Also keep in mind the design requirements typically increase with increased DSP performance.
