CCS/MSP430F5244: controller hardware multiplier

Hi,

When I was searching for some hardware multiplier code snippet I read in forums that no need to specially use hardware multiplier in the code, compiler itself uses it if we have the hardware multiplier in the controller. Is it really true?

Hi Dhananjay,

Yes, the TI compiler controls the hardware multiplier if desired. It uses the flag "--use_hw_mpy=F5" by default as seen in CCS's Project Properties -> Build -> MSP430 Compiler and can be modified inside of the Optimization tab. More information is provided in the C/C++ Compiler User's Guide (SLAU132): www.ti.com/.../slau132n.pdf

Regards,
Ryan
