EDK6446  Linux Development Kit for DaVinci

The EDK6446 development kit comes with the latest LEOs for DM6446 operating software. The target hardware development platform includes a DaVinci-DM644x evaluation board with a TI TMS320DM6446 processor and a 4.3” WQVGA (480x272) landscape TFT LCD touch panel, ready for 16:9 widescreen movie presentations. EDK6446 is the world's first DM6446 development kit available with LCD touch panel support.

EDK644x and LEOs for DM644x product family are made specifically for media devices in the mobile, set-top-box, and telematic applications. The video processing power enabled by the video/imaging coprocessor and the C64x+ DSP core in the DM644x is the most powerful feature of this new development platform. It provides major technical advantages in video/image/audio encoding/decoding, video analytic, image processing and sound processing. Those technical advantages can be applied in the fields of networked IP security surveillance system, wired/wireless networked digital media streaming system, automobile infotainment system, portable navigation multimedia devices, and videophones.

LEOs for EDK644x will allow you to more easily and quickly develop digital media applications. Application code can be written, with easy access via LEOS APIs to the C64x+ DSP core. No detailed DSP knowledge is required to access DSP functions.
