OMAP (Open Multimedia Applications Platform) is a series of image/ video processors developed by Texas Instruments. They are a category of proprietary system on chips (SoCs) for portable and mobile multimedia applications. OMAP devices generally include a general-purpose ARM architecture processor core plus one or more specialized co-processors. Earlier OMAP variants commonly featured a variant of the Texas Instruments TMS320 series digital signal processor.
The platform was created after December 12, 2002, as STMicroelectronics and Texas Instruments jointly announced an initiative for Open Mobile Application Processor Interfaces (OMAPI) intended to be used with 2.5 and 3G mobile phones, that were going to be produced during 2003. (This was later merged into a larger initiative and renamed the MIPI Alliance.) The OMAP was Texas Instruments' implementation of this standard. (The STMicroelectronics implementation was named Nomadik.)
On September 26, 2012, Texas Instruments announced that they would wind down their operations in smartphone and tablet oriented OMAP chips and instead focus on embedded platforms. The fate of OMAP therefore remains uncertain. On November 14, 2012, Texas Instruments announced that they would cut 1,700 jobs due to its shift from mobile to embedded platforms.
