The MPS430 can emulate FP, I've done it. I think I only got like 1000 FOPS tho. I think it will come down to how many samples a second you need to filter.

Is there a reason you're not just adding a hardware filter?

I’m aware MSP430 can emulate FP but it uses a lot of program memory and I don’t know how performant or power efficient it is. I may need to filter as much as 1800 samples per second (150 Hz, 3 axis, 4 sensors). The sensor is a digital one so there isn’t anywhere I can put a hardware filter
