Part Number: C64XPLUSCODECS

Hi experts,

After installing DSPLIB 3_4_0_0,the file named DSP_fft16x16.h can be find under the folder C:\ti\dsplib_c64Px_3_4_0_0\packages\ti\dsplib\src\DSP_fft16x16\c64P,

which contain the Function declaration

void DSP_fft16x16 (
const short * restrict ptr_w,
int npoints,
short * restrict ptr_x,
short * restrict ptr_y
);

but i can not find the Function source file .

Q:where is the Function void DSP_fft16x16 () source file locate?

thanks!

Hi NanShan,

I've forwarded this to the SW experts. Their feedback should be posted here.

NanShan,

The function that you are looking for is the C64x version of DSPLIB but has not been included in the C674x version. The C674x architecture is backwards compatible with the C64x+ architecture so all fixed point functions created on C64x+ also can be used on C674x without modification.

I have filed a feature request for this issue so that C674x installer provides both single precision and fixed point functions. In the meantime, you can download the C64x+ version and used that function from that library:
http://www.ti.com/tool/SPRC265 (C64XPLIS version)

Hope this helps.

Regards,
Rahul
