Where can I find more detail about the optimization of CCS' ARM Compiler? For example, I would like to know if 【Optimization Level 2 & Speed vs size 4】makes the program run faster than 【Optimization 3 & Speed vs size 2】?

It would be good to search the ARM compiler manual for the options --opt_level and --opt_for_speed. But the best way to know what those options do is to experiment with them on your program. An easy way to do that is with a feature of CCS called the Optimizer Assistant.

Thanks and regards,

Please try the menu selection View | Optimizer Assistant.
