Steps to Run the Example

• When using CCS projects to build, import the CCS project and build it using the CCS project menu (see CCS Build Project).
• When using makefiles to build, note the required combination and build using make command (see Makefile based Build)
• Launch a CCS debug session and run the executable, see Build, Load and Run
• Pick the project build configuration (RAM_FASTMATH uses the optimized implementation), build and run the example
• It will print statements as it executes the example, along with Pass/Fail information and number of cycles
• Additionally, the error between the RTS library output and the TMU output is also printed for all the inputs
• Note that the compiler will not substitute the TMU instruction for expf (or powf) computation even with -ffast-math
• This is because the TMU output is not accurate for larger positive inputs
