TMS320F2800137: Discrepancy in CPU Cycles with Different TMU Configuration Methods

Tool/software:

Hi Team,

I am observing a discrepancy in CPU cycles when configuring TMU support through different methods. When I configure TMU support from the Project Properties, the function sinf(90.2f) takes 26 CPU cycles. However, when I configure TMU support through SysConfig, the same function only takes 25 CPU cycles.

Could you please explain why this difference occurs? Additionally, what is the recommended method for configuring TMU support?
