Editing Microprocessor (section)

===Special-purpose designs===
A microprocessor is a general purpose processing entity. Several specialized processing devices have followed:

* A [[digital signal processor]] (DSP) is specialized for [[signal processing]].
* [[Graphics processing unit]]s (GPUs) are processors designed primarily for [[real-time rendering]] of images.
* Other specialized units exist for [[video processing]] and [[vision processing unit|machine vision]]. (See: [[Hardware acceleration]].)
* [[Microcontroller]]s in [[embedded system]]s and [[peripheral device]]s. 
* [[Systems on chip]] (SoCs) often integrate one or more microprocessor and microcontroller cores with other components such as [[radio modem]]s, and are used in smartphones and tablet computers.
