or 3 megapixels. Some support HD imaging. OMAP 4 The 4th generation OMAPs, OMAP 4430 (used on Google Glass), 4460 (formerly named 4440), and 4470 all use a dual-core ARM Cortex-A9 CPU, with two ARM Cortex-M3 cores, as part of the "Ducati" sub-system, for off-loading low-level tasks. The 4430 and 4460 use a PowerVR SGX540 integrated 3D graphics accelerator, running at a clock frequency of 304 and 384 MHz respectively. 4470 has a PowerVR SGX544 GPU that supports DirectX 9 which enables it for use in Windows 8 as well as a dedicated 2D graphics core for increased power efficiency up to 50-90%. All OMAP 4 come with an IVA3 multimedia hardware accelerator with a programmable DSP that enables 1080p Full HD and multi-standard video encode/decode. OMAP 4 uses ARM Cortex-A9's with ARM's SIMD engine (Media Processing Engine, aka NEON) which may have a significant performance advantage in some cases over Nvidia Tegra 2's ARM Cortex-A9s with non-vector floating point units. It also uses a dual-channel LPDDR2 memory controller compared to Nvidia Tegra 2's single-channel memory controller. OMAP 5 The 5th generation OMAP, OMAP 5 SoC uses a dual-core ARM Cortex-A15 CPU with two additional Cortex-M4 cores to offload the A15s in less computationally intensive tasks to increase power efficiency, two PowerVR SGX544MP graphics cores and a dedicated TI 2D BitBlt graphics accelerator, a multi-pipe display sub-system and a signal processor. They respectively support 24 and 20 megapixel cameras for front and rear 3D HD video recording. The chip also supports up to 8 GB of dual channel LPDDR2/DDR3 memory, output to four HD 3D displays and 3D HDMI 1.4 video output. OMAP 5 also includes three USB 2.0 ports, one lowspeed USB 3.0 OTG port and a SATA 2.0 controller. Basic multimedia applications processors These are marketed only to handset manufacturers. They are intended to be highly integrated, low cost chips for consumer products. The OMAP-DM series are intended to be used as digital media coprocessors for mobile devices with high megapixel digital still and video cameras. These OMAP-DM chips incorporate both an ARM processor and an Image Signal Processor (ISP) to accelerate processing of camera images.
