To make things more complex, a second core doesn't necessarily double the power of a processor.
The chapter introduces the key elements required in an arithmetic and logic unit of a processor.
Register files are among the most power consuming parts of a processor core.
It covers techniques for tuning the performance of a processor, such as voltage scaling.
But it's probably true that if you have memory-hungry programs that demand a lot of a processor, then a MacBook Pro is what you're really after.
Because getting information in and out of a processor takes more time than processing, there is a trade-off between creating very fast chips and keeping them busy.
It is important to remember that doubling the speed of a processor does not mean that your computer will run twice as fast.
A register in the datapath of a processor can be easily converted to a CA to realize the hardware.
But even when the core of a processor is accompanied by a large cache of memory, it still occupies only a small portion of a contemporary digital chip.
Previous Atom designs spread the work of a processor across two or three chips, a relatively power-intensive scheme that originated many years ago in Intel's PC chips.
MegaMIMO 2.0's hardware is the size of a standard router, and consists of a processor, a real-time baseband processing system, and a transceiver board.
