laura,

Is this for F2837x?

Option 1: You can simply use the math.h header file functions, and turn on the tmu_support.. and use relaxed fpu mode.. 

• TMU requires Codegen V6.2.4 or later with the compiler switch --tmu_support=tmu0

details are in the compiler guide, you can use the math.h header filer functions in your code like sin, cos etc and then enable the tmu_support, and enable relaxed fpu mode and enable optimizations.. 

so your compiler options will look like

-v28 -ml -mt --cla_support=cla0 --float_support=fpu32 -O3 --opt_for_speed=5 --fp_mode=relaxed --tmu_support=tmu0

2. Or alternatively you can use intrinsic defined in the compiler

these are described in the compiler guide above..
