General description
The 4th generation OMAPs (4430/4460/4470), 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.
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.
