TMU or Fast RTS or FPU

Hi keyur,

Clark, park use sine and cosine. If you are doing these in floating point format you can turn on the hardware floating point unit (FPU). Now you have 3 options
1. Call sin() and cos() from the standard run time support library (rts2800_fpu32.lib) that comes packaged with the CGT - these routines are more accurate than the fastRTS but take longer to execute as well
2. add in the FPUfastRTS library (C:\ti\controlSUITE\libs\math\FPUfastRTS\V100\lib\rts2800_fpu32_fast_supplement.lib) to your project, give it search precedence over the normal RTS, and call the faster sin() cos() routines.
3. if your hardware supports it, turn on the TMU support (--tmu_support=tmu0 and --fp_mode=relaxed) in addition to FPU support (--fpu_support=fpu32) and then call the sin(), cos()- what the compiler does in this case is replace those calls with TMU instructions. This is the fastest of the 3 options.
