C++ .. which is basically preprocessed to C .. and is slower why, exactly: vfp tables? On modern optimizing compilers? At 4Ghz vs 20Mhz?

I hope you eventually found a job you're better at.

I agree. Since they have moved to the bean counter language C++ to replace K&R "C" and assembly code they are relying on hardware to overcome software bloat. I wrote faster code on a 20 Mhz processor in assembly 20 years ago then we get at 4 Ghz now with C++.

I'm sure that the firmware code used incamera is some version of assembly, DSP is a special version of assembly code.
