hello everyone, i have a problem.  i am using a seeddsp dec6416 board which i

bought several years ago. when i bought it, they gave me a ccs. now i am using

ccs3.1. i found that i can't start dsp/bios in my ccs. when i click on the menu 'file...

I'm not sure wha tcould be happening, but you could try re-installing DSB/BIOS.

the other problem is about fixed point math functions. what happens if i define a

float and run the prog on a fixed point processor. can i call sin(x) in 6416? is there 

any limitation for x?

Fixed point processors (C64x and C64x+) can also emulate floating point in fixed point by running software algorithms. The C64x and C64x+ cores do not have a floating point unit. For that reason, the floating point operations take many instructions/cycles to be implemeted in a fixed point core.

See the range for float type on page 125 of:
