Document Summary
Contrast the pipeline cpu to the classical cpu. The classical cpu is a general purpose cpu. Because of the bus, anything can go anywhere (slight exaggeration, but it does allow a lot of flexibility on the movement of data back and forth). Cpus is if you have an application where you need data to go in lots of different directions. What is also nice about classical cpus is that they"re easier to build, so they"re not very expensive. Imagine one big bus built as a cpu. On top of a bus is different machines. Everything goes in one direction, starting at the pc (program counter). The fact that it is a bus and that it is optimized to work in this arrangement means that we can take advantage of certain things, giving us extra power and speed: It isn"t very far between one thing and another.
