It is the brain and controls all  kind of data and information any application in mobile phones circuit.It is microprocessor integrated circuit (IC) chip.<a href="http://2.bp.blogspot.com/_8JZhVVmpICU/S_ZXvz_gq-I/AAAAAAAAAZo/rIVTORB5cUg/s1600/application+processor.jpg" target="_blank"><img src="http://2.bp.blogspot.com/_8JZhVVmpICU/S_ZXvz_gq-I/AAAAAAAAAZo/rIVTORB5cUg/s320/application+processor.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" /></a> LCD controller, camera interface, serial interfaces, memory  interface,USB  controller, bluetooth and wifi controller,and more. are  controlled by an the application processor.<a href="http://4.bp.blogspot.com/_8JZhVVmpICU/S_ZYAiPyjOI/AAAAAAAAAZs/A9F0EqyvDcg/s1600/n95-3j.jpg" target="_blank"><img src="http://4.bp.blogspot.com/_8JZhVVmpICU/S_ZYAiPyjOI/AAAAAAAAAZs/A9F0EqyvDcg/s400/n95-3j.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" /></a>Here's an example of an application processor block diagram below, on  how this kind of IC works on mobile phones circuit. This kind of  an  application is commonly used on Nokia latest designed of mobile  handsets. The description of this application processor below will help  us understand how does this certain IC work.<img src="http://focus.ti.com/graphics/wtbu/blockdiagrams/l4_omap2420.gif" alt="" class="fr-fic fr-dii fr-draggable " style="" />OMAP2420 ProcessorThe OMAP2420 processor is a single-chip applications processor that  supports all cellular standards, and complements any modem or chipset  and any air interface. It is intended for high-volume wireless handset  manufacturers and is not available through distributors. The OMAP2420  includes the benefits of the OMAP 2 architecture’s parallel processing,  giving users the ability to instantly run applications and operate  multiple functions simultaneously without quality of service  compromises. The OMAP2420 includes an integrated ARM1136 processor (330  MHz), a TI TMS320C55x™DSP (220 MHz), 2D/3D graphics accelerator, imaging  and video accelerator, high-performance system interconnects and  industry-standard peripherals.GraphicsThe OMAP2420 processor embeds Imagination Technologies' POWERVR MBX™  graphics core, making it the first applications processor to support  OpenGL ES® 1.1 and OpenVG™, providing superior graphics performance and  advanced user interface capabilities. TI is enabling sophisticated and  dynamic images with "smart pixel" technology offered via OpenGL ES 1.1.  This unique technology allows each pixel in an image to be programmed  individually, giving developers the power to create rich effects with  cinematic realism. Users will now experience "life-like" facial  features, advanced reflection effects and multi-textured backgrounds in  the mobile environment.Multimedia enhancements made in the OMAP2420 include an added imaging   and video accelerator for higher-resolution still capture applications,   multi-megapixel cameras and full-motion video encode and decode with   VGA resolution of 30 frames per second. An added TV video output   supports connections to television displays for displaying images and   video captured from the handset. 5-Mb internal SRAM also boost streaming   media performance.              Access to the OMAP Developer Network  also provides an extensive range of  programs and media components that  manufacturers can use for  differentiating and delivering products to  market fast.Key Features:<ul> <li data-xf-list-type="ul">Dedicated 2D/3D graphics accelerator at 2 million polygons per  second</li> <li data-xf-list-type="ul">Added imaging and video accelerator enables high-resolution still   image capture, larger screen sizes and higher video frame rates</li> <li data-xf-list-type="ul">Supports high-end features including 4+ megapixel cameras,   VGA-quality video, high-end interactive gaming functionality and   analog/digital TV video output</li> <li data-xf-list-type="ul">5-Mb internal SRAM boosts streaming media performance</li> <li data-xf-list-type="ul"> Software compatibility with previous OMAP processors</li> <li data-xf-list-type="ul">Parallel processing ensures no interruptions or degradation of  service with simultaneously running applications</li> <li data-xf-list-type="ul">Optimized power management companion chip, TWL92230                                 12 mm x 12 mm, 325-ball MicroStar BGA™, 0.5-mm pitch</li> </ul></blockquote>
