Actually this embedded micro sits in a highly elliptical LEO satellite, to calculate the orbit parameters based on the apogee values on a real time basis. And when it is over my house it is supposed to give me the co-ordinates of a target I need and in turn I need to upload GPS data to correct flight path deviation and so on...

So I guess, a Cray (why a dying power?) or better on chip would be appropriate!!
