Processor (computing)
In
The term is frequently used to refer to the central processing unit (CPU), the main processor in a system.[7] However, it can also refer to other coprocessors, such as a graphics processing unit (GPU).[8]
Traditional processors are typically based on silicon; however, researchers have developed experimental processors based on alternative materials such as
Moore's law
Moore's law, named after Gordon Moore, is the observation and projection via historical trend that the number of transistors in integrated circuits, and therefore processors by extension, doubles every two years.[16] The progress of processors has followed Moore's law closely.[17]
Types
.Graphics processing units (GPUs) are present in many computers and designed to efficiently perform computer graphics operations, including linear algebra. They are highly parallel, and CPUs usually perform better on tasks requiring serial processing. Although GPUs were originally intended for use in graphics, over time their application domains have expanded, and they have become an important piece of hardware for machine learning.[18]
There are several forms of processors specialized for machine learning. These fall under the category of
Physics processing units (PPUs) are built to efficiently make physics-related calculations, particularly in video games.[19]
Field-programmable gate arrays (FPGAs) are specialized circuits that can be reconfigured for different purposes, rather than being locked into a particular application domain during manufacturing.
