The method to speed up the execution processing time is as follows. (1) Set the optimization option to speed priority Set [C/C++ Build]>[Settings]> [Compiler]>[Optimization] to「Optimize for speed」. (2) Set local variables so that they cannot be assigned to the stack. [C / C ++ Build]> [Settings]> [Compiler]> [Optimization] Uncheck 「Allocate all local variables not declared register to the stack」. (3) Do not standardize register save / return routines for function entry / exit [C / C ++ Build]> [Settings]> [Compiler]> [Code Generation] Check 「Disable optimization by register push/pop routine」. However, if this setting is used, the code size may increase. (4) If you are using multiplication / division, use a multiplication / division device. [C / C ++ Build]> [Settings]> [Linker]> [General] Check 「Enable multiplication and division accelerator」. From this, the library using the multiplication / division device (coprocessor) will be linked. However, if you use DMA, you cannot use DMA and coprocessor at the same time, so it cannot be applied.
