Multimedia / Gaming. IVA 2+ a second-generation, power-optimized version of TI's imaging, video and audio accelerator used in TI's DaVinci™ technology provides up to 4x performance improvement in multi-media processing versus previous OMAP processors. The increased capabilities of the IVA2+ enables multi-standard (MPEG4, H264, Windows Media Video, RealVideo etc.) encode and decode at DVD resolutions. With the advanced multimedia capabilities of the OMAP3430 a multi-standard DVD-quality camcorder can be added to a phone for the first time. In addition, the ARM's vector floating-point acceleration, coupled with the OMAP3430's dedicated 2D/3D graphics hardware accelerator, provides outstanding gaming capabilities.

All features of the microprocessor are not exploited in the n900. Some of the missing feature may be possible to exploit with additional software, and some are not implemented in external hardware.

Summary

The OMAP3430 contains a ARM® Cortex™-A8 superscalar microprocessor core.

Features

  • IVA2+ accellerator can encode/decode (MPEG4, H264, Windows Media Video, RealVideo etc.) at DVD resolutions.
  • vector floating-point acceleration,
  • dedicated 2D/3D graphics hardware accelerator

Graphics. The OMAP3430 processor embeds Imagination Technologies' POWERVR SGX™ graphics core, and supports OpenGL ES® 2.0 and OpenVG™, providing superior graphics performance and advanced user interface capabilities. TI is enabling sophisticated and dynamic images with "smart pixel" technology offered via OpenGL ES 2.0.
