I recently unrolled an insertion sort and on 60 items it was twice as slow as the looped version. I'm guessing that's because it was too big for the instruction cache, being 1032 KB. First, does that seem a likely explanation? If so, to avoid that problem, do I just …

What I've learned so far: An OS may trigger a software interrupt by executing a system call. According to what I read online, this is implemented via special instructions such as INT that the CPU can execute. I also understand how interrupts get handled by the interrupt service routine. My …

My book says that interrupt chaining is a "compromise between the overhead of a huge interrupt table and the inefficiency of dispatching to a single interrupt handler." I understand how the interrupt vector table works & why dispatching to a single interrupt handler is worse than choosing from an array. …
