missing double precision functions in dsplib

Kee Yong Ting

Hi, I am using c6748 processor, and I tried to use DSPF_dp_bitrev_cplx from dsplib 3.1.1.1. The strange thing is, when I open the include file dsplib.h, the included function headers are all in single precision, and the double precision functions are missing. May I know where can I find the double precision library?

The DSPLIB for C6748 contains only single precision functions. There are some functions provided as part of the C66x DSPLIB that support double precision format.

Hi, I have installed the following dsplib:

c674x-dsplib_1_03_00_01

dsplib_c64Px_3_1_1_1

dsplib_c66x_3_1_1_1

dsplib_c674x_3_1_0_0

dsplib_c674x_3_1_1_1

and so far I have yet to find any following functions

bitrev_index

DSPF_dp_bitrev_cplx

DSPF_dp_cfftr2

DSPF_dp_icfftr2

These function has being stated in dsplib guide, so do they exist? Thank you.
