Wow -- Floating point FPU

Post by basicchip » Wed Aug 07, 2013 11:48 pm

One of our consulting projects is using the LPC4078, which is an M4 ARM that can run 120 MHz and includes an FPU (floating point unit)

I found the code and libraries to use that and built a version of BASIC firmware with it and did some quick bench marks.

2000000 integer operations 0.1 seconds

2000000 floating adds 1.9 seconds

2000000 floating adds with FPU 0.44 seconds

This may need to become the next product

Not bad for a small ARM -- close to 5 MFLOPs
