omap family

the galaxy nexus, example of smartphone omap 4460 soc

the omap family consists of 3 product groups classified performance , intended application:

high-performance applications processors
basic multimedia applications processors
integrated modem , applications processors

further, 2 main distribution channels exist, , not parts available in both channels. genesis of omap product line partnership cell phone vendors, , main distribution channel involves sales directly such wireless handset vendors. parts developed suit evolving cell phone requirements flexible , powerful enough support sales through less specialized catalog channels; omap 1 parts, , many omap 3 parts, have catalog versions different sales , support models. parts obsolete perspective of handset vendors may still needed support products developed using catalog parts , distributor-based inventory management.

high-performance applications processors

these parts intended use application processors in smartphones, processors powerful enough run significant operating systems (such linux, android or symbian), support connectivity personal computers, , support various audio , video applications.

omap 1

the omap 1 family started ti-enhanced arm core, , changed standard arm926 core. included many variants, distinguished according manufacturing technology (130 nm except omap171x series), cpu, peripheral set, , distribution channel (direct large handset vendors, or through catalog-based distributors). in march 2009, omap1710 family chips still available handset vendors.

products using omap 1 processors include hundreds of cell phone models, , nokia 770 internet tablets.

omap171x – 220 mhz arm926ej-s + c55x dsp, low-voltage 90 nm technology
omap162x – 204 mhz arm926ej-s + c55x dsp + 2 mb 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

omap 2

these parts marketed handset vendors. products using these include both internet tablets , mobile phones:

omap2431 – 330 mhz arm1136 + 220 mhz c64x dsp
omap2430 – 330 mhz arm1136 + 220 mhz c64x dsp + powervr mbx lite gpu, 90 nm technology
omap2420 – 330 mhz arm1136 + 220 mhz c55x dsp + powervr mbx gpu, 90 nm technology

omap 3

the 3rd generation omap, omap 3 broken 3 distinct groups: omap34x, omap35x, , omap36x. omap34x , omap36x distributed directly large handset (such cell phone) manufacturers. omap35x variant of omap34x intended catalog distribution channels. omap36x 45 nm version of 65 nm omap34x higher clock speed.

the omap 3611 found in devices bookeen s cybook odyssey licensed crippled version of ompa 3621, both same silicon (as marking same) officially 3611 sold able drive e-ink screen , not have access iva & dsp.

the video technology in higher end omap 3 parts derived in part davinci product line, first packaged higher end c64x+ dsps , image processing controllers arm9 processors last seen in older omap 1 generation or arm cortex-a8.

not highlighted in list below each omap 3 soc has image, video, audio (iva2) accelerator. these units not have same capabilities. devices support 12 megapixel camera images, though support 5 or 3 megapixels. support hd imaging.

omap 4

the ti ducati sip core video acceleration , accelerated image processing.

the 4th generation omaps, omap 4430 (used on google glass), 4460 (formerly named 4440), , 4470 use dual-core arm cortex-a9 cpu, 2 arm cortex-m3 cores, part of ducati sub-system, off-loading low-level tasks. 4430 , 4460 use powervr sgx540 integrated 3d graphics accelerator, running @ clock frequency of 304 , 384 mhz respectively. 4470 has powervr sgx544 gpu supports directx 9 enables use in windows 8 dedicated 2d graphics core increased power efficiency 50-90%. omap 4 come iva3 multimedia hardware accelerator programmable dsp enables 1080p full hd , multi-standard video encode/decode. omap 4 uses arm cortex-a9 s arm s simd engine (media processing engine, aka neon) may have significant performance advantage in cases on nvidia tegra 2 s arm cortex-a9s non-vector floating point units. uses dual-channel lpddr2 memory controller compared nvidia tegra 2 s single-channel memory controller.

omap 5

the 5th generation omap, omap 5 soc uses dual-core arm cortex-a15 cpu 2 additional cortex-m4 cores offload a15s in less computationally intensive tasks increase power efficiency, 2 powervr sgx544mp graphics cores , dedicated ti 2d bitblt graphics accelerator, multi-pipe display sub-system , signal processor. respectively support 24 , 20 megapixel cameras front , rear 3d hd video recording. chip supports 8 gb of dual channel lpddr2/ddr3 memory, output 4 hd 3d displays , 3d hdmi 1.4 video output. omap 5 includes 3 usb 2.0 ports, 1 lowspeed usb 3.0 otg port , sata 2.0 controller.

basic multimedia applications processors

gstreamer makes use of hardware acceleration through plugins provided texas instruments. api dmai (davinci multimedia application interface).

these marketed handset manufacturers. intended highly integrated, low cost chips consumer products. omap-dm series intended used digital media coprocessors mobile devices high megapixel digital still , video cameras.

the image signal processor (isp) used accelerate processing of camera images.

omap331 – arm9
omap310 – arm9
omap-dm270 – arm7 + c54x dsp
omap-dm299 – arm7 + image signal processor (isp) + stacked mddr sdram

omap-dm510 – arm926 + isp + 128 mb stacked mddr sdram
omap-dm515 – arm926 + isp + 256 mb stacked mddr sdram
omap-dm525 – arm926 + isp + 256 mb stacked mddr sdram

integrated modem , applications processors

an omap 850 in htc wizard

these marketed handset manufacturers. many of newer versions highly integrated use in low cost cell phones.

omapv1035 – single-chip edge (was discontinued in 2009 ti announced baseband chipset market withdrawal).

omap710 – 133 mhz arm925 + gsm/gprs digital baseband

omap l-1x

the omap l-1x parts marketed through catalog channels, , have different technological heritage other omap parts. rather deriving directly cell phone product lines, grew video-oriented davinci product line removing video-specific features while using upgraded davinci peripherals. notable feature use of floating point dsp, instead of more customary fixed point one.

the hawkboard uses omap-l138

omap-l137 – 300 mhz arm926ej-s + c674x floating point dsp
omap-l138 – 300 mhz arm926ej-s + c674x floating point dsp
