Don't forget, also, that the ARM11 in the BCM2835 is actually just a secondary processor; the main CPU is a blisteringly fast dual-core Videocore 4, which lots of interesting DSPish and vector processing instructions. (You can call out to it from the ARM.) See: http://maazl.de/project/vc4asm/doc/index.html http://maazl.de/project/vc4asm/doc/index.html And if you're into shader programming, the GPU has a 24 GFLOP shader unit. https://github.com/hermanhermitage/videocoreiv-qpu https://github.com/hermanhermitage/videocoreiv-qpu Only suitable for very specialised purposes, but astonishingly fast.
