Texas Instruments OMAP (Open Multimedia Application Platform) is a category of proprietary microprocessors that have capabilities for portable and mobile multimedia applications and are developed by Texas Instruments. Many mobile phones use OMAP microprocessors, including most of Nokia's N-series range. Phones known to use OMAP include the N90, N91, N92, N95, N82, E61, E62, E63, and many other Nokia and Samsung devices (such as the Nokia N800/N810 and N900 Internet Tablets). The Palm Pre and Motorola Droid also use an OMAP processor (the OMAP3430). Others to use an OMAP SoC include the Sony Ericsson Satio and the Samsung OMNIA HD. Some of the processors in the OMAP family contain a dual-core architecture consisting of both a general-purpose host ARM processor and one or more DSP. The digital signal processor featured is commonly a variant of the Texas Instruments TMS320 series DSPs.

Processor families
The OMAP family consists of three product groups classified by performance and intended application: "High Performance", "Basic Multimedia", and "Modem and Applications".
Additionally, there are two primary distribution channels - not all parts being available in both channels. The genesis of the OMAP product line is from partnership with cell phone vendors, and the main distribution channel involves sales directly to such wireless handset vendors. Parts developed to suit evolving cell phone requirements are flexible and powerful enough to support sales through less specialized catalog channels; some OMAP1 parts, and many OMAP3 parts, have catalog versions with different sales and support models. Parts that are obsolete from the perspective of handset vendors may still be needed to support products developed using catalog parts and distributor-based inventory management.
Recently, the catalog channels have received more focus, with OMAP35x and OMAP-L13x parts being marketed for use with various applications where capable and power-efficient processors are useful.
"High performance"
These are parts originally intended for use as application processors in smart phones, with processors hefty enough to run significant operating systems (such as Linux or Symbian), support connectivity to personal computers, and support various audio and video applications.
OMAP1
The OMAP1 family started with a TI-enhanced ARM core, and then switched to a standard ARM926 core. It included numerous variants, most easily distinguished according to manufacturing technology (130 nm except for the OMAP171x series), CPU, peripheral set, and distribution channel (direct to large handset vendors, or through catalog-based distributors). In March 2009, the OMAP 1710 family chips are still available to handset vendors.
Products using OMAP1 processors include hundreds of cell phone models, and the Nokia 770 Internet Tablets.
- OMAP171x - 220 MHz ARM926EJ-S + C55x DSP, Low-voltage 90 nm technology
- OMAP162x - 204 MHz ARM926EJ-S + C55x DSP + 2MB Internal SRAM, 130 nm technology
- OMAP5912 - catalog availability version of OMAP1621 (or OMAP1611b in older versions)
- OMAP161x - 204 MHz ARM926EJ-S + C55x DSP, 130 nm technology
- OMAP1510 - 168 MHz ARM925T (TI-enhanced) + C55x DSP
- OMAP5910 - catalog availability version of OMAP 1510
OMAP2
These parts were never marketed except to handset vendors. Products using these include both Internet Tablets and mobile phones:
- OMAP2431 - 330 MHz ARM1136 + 220 MHz C64x DSP
- OMAP2430 - 330 MHz ARM1136 + 220 MHz C64x DSP + PowerVR MBX lite GPU
- OMAP2420 - 330 MHz ARM1136 + 220 MHz C55x DSP + PowerVR MBX GPU
OMAP3
The OMAP3 is broken into 3 distinct groups: the OMAP34x, the OMAP35x, and the OMAP36x. OMAP34x and OMAP36x are distributed directly to large handset (such as cell phone) manufacturers. OMAP35x is a variant of OMAP34x intended for catalog distribution channels. The OMAP36x is a 45nm version of the 65nm OMAP34x with higher clock speed.[1]
The video technology in the higher end OMAP3 parts is derived in part from the DaVinci product line, which first packaged higher end C64x+ DSPs and image processing controllers with ARM9 processors last seen in the older OMAP1 generation.
Not highlighted in the list below is that each OMAP3 processor has an "Image, Video, Audio" (IVA2) accelerator. These units do not all have the same capabilities. Most devices support 12 megapixel camera images, though some support 5 or 3 megapixels. Some support HD imaging.
The OMAP3 3430 is used by the Motorola Droid, Palm Pre, and Nokia N900 cellular phones.

"Basic multimedia"
These are marketed only to handset manufacturers. They are intended to be highly integrated, low cost chips for consumer products. The DMx series are intended to be used as digital media coprocessors for mobile devices with high megapixel digital still and video cameras.

- OMAP-DM525 - ARM926 + ISP + 256Mb stacked mDDR SDRAM
"Modem and applications"
These are marketed only to handset manufacturers. Many of the newer versions are highly integrated for use in very low cost cell phones.
- OMAPV1035 - single-chip EDGE (was discontinued in 2009 as TI announced baseband chipset market withdrawal).
- OMAPV1030 - EDGE digital baseband
- OMAP850 - 200 MHz ARM926EJ-S + GSM/GPRS digital baseband + stacked EDGE co-processor
- OMAP750 - 200 MHz ARM926EJ-S + GSM/GPRS digital baseband + DDR Memory support

- OMAP710 - 133 MHz ARM925 + GSM/GPRS digital baseband
OMAP L-1xx
The OMAP L-1xx parts are marketed only through catalog channels, and have a different technological heritage than the other OMAP parts. Rather than deriving directly from cell phone product lines, they grew from the video-oriented DaVinci product line by removing the video-specific features while using upgraded DaVinci peripherals. A notable feature is use of a floating point DSP, instead of the more customary fixed point one.
- OMAP-L137 - 300 MHz ARM926EJ-S + C674x floating point DSP
- OMAP-L138 - 300 MHz ARM926EJ-S + C674x floating point DSP
