Where the prediction fails, a component called the jump execution unit (JEU) moves the end marker from the last μop in line to the μop that was predicted incorrectly. This signals that all μops behind the end marker should be ignored and can be overwritten by new μops. The BTB is told that its prediction was incorrect, and that information becomes part of its future predictions. che a L2 C If a μop needs data from memory, the execute unit skips it, and the processor looks for the information first in the nearby L1 cache.
And it’s not, really. Mathematicians have pointed out the similarities between the Towers of Hanoi and binary computations, geometry, and the exact duplication of a function called the binary carry sequence. But never mind all that. Let’s play the game using only three rings, or disks, as we’ve drawn them here: A B C A B C A B C A B C A B C A B C A B C A B C 1. Take the top, purple disk and place in the empty B spot. 2. Place the green disk on C. 3. Put the purple disk from position B and put it on top of the green disk.
1 1 Residential power transformer 2 2 At a power station, steam generated from burning coal or heat from a nuclear plant turns a shaft within an electric dynamo. The shaft is attached to a rotor covered with thousands of wires called bushings. The rotor turns inside two permanent stator magnets otor Rotor whose fields generate high-voltage electricity gnet Stator Magnet in the bushings that is transmitted as alternating current on the public power grid to homes and businesses.
