A CPU has a five-stage pipeline and runs at 1 GHz frequency. Instruction fetch happens in the first stage of the pipeline. A conditional branch instruction computes the target address and evaluates the condition in the third stage of the pipeline. The processor stops fetching new instructions following a conditional branch until the branch outcome ( Read more... )

I just read P, NP and mathematics - a computational complexity perspective. It was really interesting, but is this paper... respectable? If so it's a great summary of the things that are happening in mathematics these days.

I'm studying "computability" and my text book uses this minimal programing language called "RAM programing" It has just seven commands ( Read more... )
