KL02 SOC based FRDMKL02Z board Floating Point support

We are working on FRDMKL02Z board . Using MQXLite and PE for firmware development .

Some of the functionality within the code requires floating point operations to be supported e.g. atof() API , floating point arithmetic .

But when we perform floating point operations as described above m_text size increases significantly I mean in terms of 10K size difference.

 

Out initial analysis is as ARM Cortex M0 is used in KL02 series SOC and M0 does not any support FPU , so software based floating point algorithms are triggered which increases the code size (m_text ) .

 

We have limited FLASH memory on the EVM and need to support mode code on the same platform .

 

Can you guys recommend any solution to above situation .

 

Also its will be great if you can low power Freescale SOC which supports FPU .

 

 

Thanks In advance .
