Introduction

This example calls the mathlib trignometric functions for different angles between 0 to 2Pi

• Calls trignometric functions with SDK mathlib APIs and CLANG mathlib APIs
• Compares the performance between the two versions and prints the time taken and the error

Supported Combinations

Parameter	Value
CPU + OS	r5fss0-0 nortos
Toolchain	ti-arm-clang
Board	am243x-evm
Example folder	examples/mathlib/benchmark/mathlib_benchmark.c

Steps to Run the Example

• When using CCS projects to build, import the CCS project for the required combination and build it using the CCS project menu (see Using SDK with CCS Projects).
• When using makefiles to build, note the required combination and build using make command (see Using SDK with Makefiles)
• Launch a CCS debug session and run the executable, see CCS Launch, Load and Run
