TMS320C55x DSP function floating point

Other Parts Discussed in Thread: TMS320C5515

Hi,

I'm trying to use the Sparc100: TMS320C55x DSP Library on my TMS320C5515 board. When I try the funtion sqrt_16 with input array x[5] = {1, 4, 9, 16, 25}, the result I got is an array r[5] = (222, 384, 558, 736, 915), instead of expected result of {1, 2, 3, 4, 5}. I guess there must be some floating point issue there. So can someone explain for me?

Thanks,

Qingkun
