Intel Atom
Intel Atom is a line of IA-32 and x86-64 instruction set ultra-low-voltage processors by Intel Corporation designed to reduce electric consumption and power dissipation in comparison with ordinary processors of the Intel Core series. Atom is mainly used in netbooks, nettops, embedded applications ranging from health care to advanced robotics, mobile Internet devices (MIDs) and phones. The line was originally designed in 45 nm complementary metal–oxide–semiconductor (CMOS) technology and subsequent models, codenamed Cedar, used a 32 nm process.

The first generation of Atom processors are based on the Bonnell microarchitecture. On December 21, 2009, Intel announced the Pine Trail platform, including new Atom processor code-named Pineview (Atom N450), with total kit power consumption down 20%. On December 28, 2011, Intel updated the Atom line with the Cedar processors.
In December 2012, Intel launched the 64-bit Centerton family of Atom CPUs, designed specifically for use in servers. Centerton adds features previously unavailable in Atom processors, such as Intel VT virtualization technology and support for ECC memory. On September 4, 2013, Intel launched a 22 nm successor to Centerton, codenamed Avoton.
