DVI aggregation manager media processors

The DVI AM media processor from Texas Instruments Incorporated (TI) is an ARM® Cortex-A8-based architecture providing audio, camera and video media interfaces. Device vendors wishing to enable HD video streaming should use TI’s OMAP3530 media processor, which incorporates an HD video accelerator. Device vendors not requiring HD (720p) video streaming should use the lower cost AM3517, which supports HD (720p/1080i) UIs over DVI but does not incorporate an HD video accelerator. Both media processors come with recent Linux distributions (which can support Ubuntu/Android UIs) and are code compatible.

Device vendors looking for increased video performance up to full HD 1080p should use the OMAP4430 processor, which is an ARM Cortex-A9 dual-core processor.

HD video streaming

The OMAP3530 high-performance, low-power mobile applications processor integrates the ARM Cortex-A8 processor with TI’s C64x+DSP hardware-accelerated video processor and relevant peripherals.

The OMAP35x evaluation module includes open-source Linux and drivers, along with Code Sourcery tools and a digital video software development kit (DVSDK). Included in the DVSDK are production-ready, easy-to-use audio and video codecs for hardware-accelerated video processors based on TI DaVincitechnology. These codecs are preintegrated with Linux and network peripherals to support real-time 720p video streaming. SD codecs are available free from TI, while HD codecs are available through TI’s Third-Party Network.

The OMAP4430 processor integrates ARM Cortex-A9 dual cores with a hardware-accelerated video processor. It supports full HD 1080p video streaming (or 720p two-way video teleconferencing), among other multimedia-rich features.

Low power aggregation manager processors

For lower power/cost designs, TI’s Stellaris® ARM Cortex-M3-based microcontroller is available. In addition to simultaneous interfaces, including Ethernet MAC/PHY and USB On-The-Go, the LM3S9B96 development kit adds several features that enhance the overall user experience, such as an integrated 3.5-inch, color QVGA LCD with a resistive touch interface, a thumbwheel potentiometer (for menu navigation), a user LED and pushbutton, a MicroSD card slot, and 1 MB of serial flash memory. The LM3S9B96 development kit comes with an expansion board that can work with TI’s CC2530 ZigBee SoC, CC2540 Bluetooth low energy SoC and CC2570 ANT Network Processor (NWP). Software tools suite choices in the kit include:

  • Evaluation versions of ARM’s RealView microcontroller development kit

  • IAR Embedded Workbench Kickstart Edition

  • Code Red Technologies’ Red Suite

  • CodeSourcery Sourcery G++ GNU tools
