Huang,

Most of the math functions that you are looking for are part of the C6000 DSP compiler RTS library(rts6740.lib) but if you are looking for optimized implementation of the trignometric, exponential and logartihmic and arithmetic functions please take a look at Math lib details given below:

Please let us know if this suffices your requirement.

Regards,

Rahul

thanks! Rahul

i installed the package, according to the user guide, i must insert "-l C67xfastMath.lib" into linker command file, but i'm using c6runlib to compile my code, where can i find the linker command file ?

C6Run based builds are done using make files. Refer to this wiki article to link the mathlib with C6run
