MCU-PLUS-SDK-AM243X: Optimized trigonometric functions on TI ARM cores

Part Number: MCU-PLUS-SDK-AM243X
Other Parts Discussed in Thread: MATHLIB

Tool/software:

In respsonse to the feedback that I had received via another thread here:

PROCESSOR-SDK-J721E: Optimized Trigonometric Functions on TI Arm Cores - Processors forum - Processors - TI E2E support forums

I would like to port the fast math functionalities that are supported from the above mentioned library from AM43X platform on to the R5F core of TDA4 platform. 

So could you please let me know where exactly can I find the definition of the following functions from the fast math librabry ?

ti_arm_sin(), ti_arm_cos(), ti_arm_sincos(), ti_arm_asin(), ti_arm_acos(), ti_arm_atan(), and ti_arm_atan2()

Thanks !
