- Okay, here goes:
-
- FPU:
- Slow for 3D (too high accuracy). Best where high accuracy is useful
- together with a lot of calculations, for example in a high quality
- raytracer. Also, floating point operations in C are best performed by the
- FPU because C, like the FPU, uses IEEE floating point.
-
- Blitter:
- Does one thing (and, on the Falcon, not too well): Copies data from one
- memory address to another, with the option of doing some shifts and stuff
- while doing it. For some strange reasong, there are problems blitting
- directly from the DSP host port.
-
- Keyboard and other processors:
- Short answer: forget about it.
- Longger answer: They are too slow and too sepcific to use for anything
- apart from for what they were designed.
