Hi all,

I am currently using the LPC1768 development board for a project. Since I am using a lot of floating point calculations, I wish to replace the MCU with a floating point processor. Is there an equivalent development board for the LPC1768 which have a floating point ALU?
Is it possible to use the same MBED code if I change the MCU? and are there any advantages of using a fixed point processor when compared to a fixed point processor?

Any help would be highly appreciated.

 

Look for stm32f boards,
for example http://www2.st.com/content/st_com/e...val-tools/stm32-mcu-nucleo/nucleo-f401re.html

It is mbed enabled and your software could be used with minor modifications depending on needed I/O peripherals.
Price is 10+$

Your best luck is likely with NXP: floating point units don't show up until CM4 so I would start with NXP CM4 with the same packaging as LPC1768.

BTW, those are single precision fpus. they suck wind if your code uses double precision floating point math.

Many times, it is much better to use fixed point math and CMSIS provides a very nice package for that, with cross-platform (=CM0/1/3/4) compatibility.
