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
What products would you like to see?
