'''OMAP'''是由[[美國]][[德州儀器]]所推出的開放式[[多媒體]]應用平台架構（Open Multimedia Application Platform），使用[[低功耗设计|低功耗]]的[[ARM架構]][[處理器]]，可適用於移動式平台。OMAP设备一般包括一个通用的ARM架构处理器核心以及一个或多个专门的协处理器。早期的OMAP变种通常的特点是德州仪器TMS320系列数字信号处理器的变种。德州儀器最新一代多核架構是OMAP 5。

2012年9月26日，德州仪器宣布，他们将结束其在[[智能手机]]和[[平板电脑]]为导向的OMAP芯片业务，转向专注于嵌入式平台。因此，OMAP5的命运仍然不明朗。<ref>{{citation | url = http://www.reuters.com/article/2012/09/25/texasinstruments-wireless-idUSL1E8KP5FN20120925?irpc=932 | title = UPDATE 3-Texas Instruments eyes shift away from wireless | date = 25 September 2012 | publisher = Reuters | accessdate = 2012-11-23 | archive-date = 2012-11-01 | archive-url = https://web.archive.org/web/20121101134219/http://www.reuters.com/article/2012/09/25/texasinstruments-wireless-idUSL1E8KP5FN20120925?irpc=932 | dead-url = no }}</ref>2012年11月14日，德州仪器宣布，由于其从移动到嵌入式平台的转变，他们将削减1700个工作职位。<ref>{{Cite web |url=http://www.engadget.com/2012/11/14/texas-instruments-to-cut-1-700-jobs-as-part-of-shift-from-mobile/ |title=存档副本 |access-date=2012-11-23 |archive-date=2012-11-17 |archive-url=https://web.archive.org/web/20121117011351/http://www.engadget.com/2012/11/14/texas-instruments-to-cut-1-700-jobs-as-part-of-shift-from-mobile |dead-url=no }}</ref>

==OMAP家族==
[[File:Galaxy Nexus smartphone.jpg|150px|thumb|[[Galaxy Nexus]]是一个用OMAP 4460 SoC的智能手机例子]]
OMAP的產品依其功能界定可分成三種取向:
* 高效能應用處理器
* 基本多媒體應用處理器
* 整合調變解調（MODEM）與應用處理器

===高效能應用處理器===
====OMAP 1====
OMAP 1最早使用TI-enhanced ARM core，後來換成標準ARM926 core。
*OMAP171x - 220 MHz [[ARM architecture|ARM926EJ-S]] + [[Texas Instruments TMS320|C55x]] DSP, Low-voltage 90 nm technology
*OMAP162x - 204 MHz [[ARM architecture|ARM926EJ-S]] + [[Texas Instruments TMS320|C55x]] DSP + 2MB Internal SRAM, 130 nm technology
*OMAP5912 - catalog availability version of OMAP1621 (or OMAP1611b in older versions)
*OMAP161x - 204 MHz [[ARM architecture|ARM926EJ-S]] + [[Texas Instruments TMS320|C55x]] DSP, 130 nm technology
*OMAP1510 - 168 MHz [[ARM architecture|ARM925T (TI-enhanced)]] + [[Texas Instruments TMS320|C55x]] DSP
*OMAP5910 - catalog availability version of OMAP 1510

====OMAP 2====
*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
====OMAP 3====
OMAP 3可分成三種等級：OMAP34x， OMAP35x，以及 OMAP36x。

===基本多媒體應用處理器===
僅適用於手持裝置，目標是低成本的消費性產品。
*OMAP331 - ARM9
*OMAP310 - ARM9
*OMAP-DM270 - ARM7 + C54x DSP
*OMAP-DM299 - ARM7 + ISP + stacked mDDR SDRAM
===整合調變解調與應用處理器===

僅適用於手持裝置，目標是低成本的電話系統。

*OMAPV1035 - single-chip EDGE (在2009年被停止生产)
*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
*OMAP733 - 200 MHz ARM926EJ-S + GSM/GPRS digital baseband + stacked SDRAM
*OMAP730 - 200 MHz ARM926EJ-S + GSM/GPRS digital baseband + SDRAM Memory support
*OMAP710 - 133 MHz ARM925 + GSM/GPRS digital baseband

===OMAP L-1x===
OMAP L-1×部件仅通过目录渠道被销售，并有比其它OMAP部件不同的技术传承。不是直接来自手机的产品线，他们成长是从面向视频的达芬奇({{link-en|Texas Instruments DaVinci|Texas Instruments DaVinci|DaVinci}})产品线通过去除视频特定功能而使用升级的达芬奇的外围设备。一个显着的特点是使用的''浮点''DSP，而不是更多定制的定点DSP。

[[Hawkboard]]使用了OMAP-L138

*OMAP-L137 - 300 MHz ARM926EJ-S + C674x 浮点 DSP
*OMAP-L138 - 300 MHz ARM926EJ-S + C674x 浮点 DSP
