STM32F334 TrueStudio - Adding libarm_cortexM4lf_math.a Getting error: arm-atollic-eabi/bin/ld.exe: .elf section `.rodata' will not fit in region `FLASH' and region `FLASH' overflowed by 101180 byte

The size looks like around 107KB of libarm_cortexM4lf_math.a library, the total flash is 64KB in STM32F334x SoC. Could you let me know if I want to perform FFT (Fast Fourier Transformation), is there any alternative or light weight library I can use. My final goal is to read out data from LEM CTSR sensor, calculate the residual current using adc sampling and apply FFT, transfer the data over 1-wire.

More information, I want the lowest flash memory usage to make sure the code fits in flash memory.

Please help.
