sorry for a late reply

i asked wether you were working in matlab /simulink software

anyways the thing is that you need only the MSB or say 31 30 bits ,,,there
can be different approaches like

1 you data is serial ,, convert it to parallel data take your required 32
31 st bit,,,, convert it back to serial data (the two bits only) and thats
it !!!!!!!

or if you have a slicing function available in your software you can use it
,,actually its the same thing ..

by the ways you can use SHARC dsp with matlab

if this thing helps or not ,,, tell me
