34 |i.MX31 Multimedia Applications ProcessorsCore: ARM1136JF-SThe popular i.MX31 and i.MX31L multimedia applications processors are developedwith Freescale’s Smart Speed Technology to drive high performance applications atvery low power for extended battery life. The entire portfolio of i.MX processors offersa range of performance and price levels, on chip integration, and broad connectivityoptions. i.MX processors also have one of the best power-to-performance ratios ofany processor in their class. They are becoming the applications processors of choicefor portable media players, smartphones, automotive infotainment systems, V2IPphones, video surveillance systems, and many other devices. Freescale providesboard support packages (BSPs) to simplify and support development on leadingoperating systems and RTOSes. Freescale is a Gold-level Microsoft WindowsEmbedded Partner and offers BSPs for the three most recent Windows CE releases (4.2, 5.0, 6.0) Windows Mobile5.0 and the new Windows Mobile 6. The i.MX portfolio continues to grow, and new processors will be shipping inproduction this year.Features • CPU complex with L2 cache, vector floating point co-processor,and Smart Speed switch• Smart power management including support for multiple low powermodes, dynamic voltage frequency scaling, and dynamic processtemperature compensation• External memory interface with support for multipletypes of memory• Smart multimedia with support for hardware accelerated MPEG4encode, as well as pre & post processing• Display port with ability to support a variety of popular displaydevices and up to two displays simultaneously• Sensor port which provides connection to either one ortwo image sensors• System connectivity, including USB high speed OTG, CSPIs,I 2 C, PCMCIA, ATA, UARTs• 2D/3D graphics acceleration (only available on i.MX31)• Board support packages for the major operating systemsi.MX31 Block DiagramBenefits • High performance with 32-bit DDR and L2 cache• Long battery life for mobile applications• Ability to boot from NAND flash• MPEG4 playback at 30 fps VGA resolution• Interactive console-like gaming experience with OpenGL-ES basedgraphics acceleration• On chip LCDC eliminates the need for timing chips when usingcertain displays• Capture, process, and display of moving and still objects• High level of integration simplifies overall board design andlowers BOM costArrow Electronics ARM Solutions1-866-910-3650
