I have an ARM development system, but haven't yet explored it. This makes me very interested in learning more about it. ;-)Great. Perhaps you'll discover a co-favourite CPU. ;-)
I expect to. I looked at the ARM architecture when it first came out, and was impressed with the simplicity and power. Putting predicate bits on each instruction is certainly an interesting approach, since it can be quite useful--but I wondered at the time if it was useful enough to take up an entire half of the coding space. It reminded me of the way that older architectures used a bit to flag indirect addresses, which is unthinkable in a world in which address bits are precious and indirection is both slow and uncommon. -michael NadaNet networking for Apple II computers!
