Computerphile at its best, here tackling the topic of additional (supplementary) processors, like FPUs, GPUs, sound processors, etc., to which CPUs outsource some of their work under specific circumstances. Even speaking as somebody who’s upgraded a 386/SX to a 386/DX through the addition of a “math co-processor” (an FPU) and seeing the benefit in applications for which floating point arithmetic was a major part (e.g. some early 3D games), I didn’t really think about what was really happening until I saw this video. There’s always more to learn, fellow geeks!
