WebJun 25, 2013 · So the scheduling is trickier. In CISC, there are often mixes of simpler instructions, and more complicated instructions that take longer. So in a pipeline there are things called hazards that can create problems for smooth pipelining. X86 Floating Point instructions would be longer than x86 load or store, for example. WebMay 16, 2013 · Diagrams of CPU Pipelines. The i486 had a 5-stage pipeline that worked well. The idea was very common in other processor families and works well in the real world. The Pentium pipeline was even better than the i486. It had two instruction pipelines that could run in parallel, and each pipeline could have multiple instructions in different stages.
