Optimization of speed by --code_state=16

Satoshi Shinohara

I'm using RM48L950ZWT(Rev.C) and CCSv6.1.1.

I found the wiki site for optimization in ARM compiler.

http://processors.wiki.ti.com/index.php/ARM_compiler_optimizations#Recommended_performance_options_for_Cortex-RF_devices

It says that "--code_state=16" is recommended for performance option for Cortex-RF device.

Should I use "--code_state=16" option for optimization of speed?

Yes, using thumb2 code (16/32 BIS) will generally result in better performance. However, please note that all exception handlers must be ARM code (32 BIS), so you cannot apply the --code_state=16 option to the entire CCS code project.
