The new TI’s DaVinci DM37x Video Processors (TMS320DM3730 and TMS320DM3725) is powered by 1 GHz ARM Cortex-A8 and 800MHz C64x+ DSP core, and have integrated 3D graphics processor (DM3730 only), imaging and video accelerator (IVA), USB 2.0, MMC/SD memory card, UART and many more. DaVinci DM3730 and DM3725 Video Processors are pin-to-pin compatible with Sitara AM37x devices and software compatible with the OMAP35x processors. Customers moving to the DM3730 from the OMAP3530 can look forward to a 50 percent increase in ARM performance, a 40 percent increase in DSP performance, double the graphics performance and uses approximately 40 percent less power.

Development tools for TI’s DaVinci DM3730 and DM3725 Video Processors

To accelerate time to market and minimizing development costs, TI offers TMDXEVM3730 EVM (evaluation module), which includes a TI Bluetooth WiFi module. The SDK (software development kit) includes Linux kernel 2.6.32 board support package complete with graphical user interface, graphics, applications, demonstrations and development utilities. The SDK also offers a royalty-free library of DSP-optimized signal processing algorithms accessible from the ARM processor through a set of easy-to-use application programming interfaces (APIs). The DSP library contains more than 80 algorithms, including multi-media decoders and encoders, math functions, digital filtering including Fast Fourier Transform (FFT), and image processing including image filtering and analysis.

Support for the Linux and Android operating systems is available today. Windows CE support will be available in fourth quarter of this year.

Customers may also develop on the BeagleBoard-xM, a low-cost, open-source community board equipped with the DaVinci DM3730 Video Processor.
