A New Proccesor
Imagine a processor where all computations are done before you ask for them. It sounds something like quantum computing, doesn't it?
Here's the idea: the instruction doesn't have any arithmetic operators, instead, it has a bunch of read only registers which always have some computation in them. For example, register a1 might be the sum of registers g1 and g2. So, instead of coding add g3, g1, g2, you would use mov g3, a2.
That looks cumbersome, so what's the point? Well, faster, cheaper, hardware, I hope. A whole mess of switching logic could be foregone in this scheme, shortening the instruction pipeline.
Writing a compiler for this architecture might be painful, but I think it sounds like fun. It's something to think about at least.# -
