How to use inline function of c67xmathlib??

hello everybody.

I use c67xmathlib_2_01_00_00 for C6748.

I am from the fastmath library provides test procedure found in an inline function calculates the clock soon.so the plan in my program using inline functions to improve the computation efficiency.

I am in the header file c67fastmath_i.h and C67xfastmath.lib, compile error:variable "V" has already been initialized.In order to resolve this error, I will inline functions proposed to generate a new inline.h.I am in the header file inline.h and C67xfastmath.lib,CompileOK.

I tested these inline functions, but found the ratio of c67fastmath.h function provided by the operating speed of consuming a lot more.

For example:

c67xmathlib_2_01_00_00\src\dp\sqrtdp.Test results are as follows:

RTS    ASM      C         Inlined   vector

1277   369     388       131       127.

The sprt_i in the inline.h header files, into my program.

double aa = 232.33563;

double b1,b2,b3;

b1 = sqrt(aa);    700clock

b2 = sqrtdp(aa); 360clock

b3 = sqrtdp_i(aa); 1900clock

I analyze out the reasons for this phenomenon.hellp me.

Thanks.
