DM355 Digital Video Evaluation Module (DVEVM)

       DM355 處理器專門支援高畫質視訊,內建視訊/影像協同處理器使其具備強大效能,耗電量也很低。MJCP 能以每秒 30 格畫面的速率,針對 720p 解析度的高畫質視訊執行 MPEG-4 簡單類別 (Simple Profile) 編碼與解碼,或以每秒 5000 萬個像素的速率執行 JPEG 編碼或解碼。視訊處理次系統是所有 DaVinci 處理器都具備的功能,可將預視引擎、直方圖統計 (histogram)、畫面縮放和螢幕功能顯示 (OSD) 等功能全部整合到硬體。MJCP 提供相當於 400MHz DSP 的效能以支援高畫質視訊,視訊處理次系統則約等於 240MHz DSP,兩者的總效能最高相當於 640MHz DSP;除此之外,DM355 還有高達 270MHz 的 ARM 處理效能,可進行產品差異化。DM355 包含多種精心選擇的週邊,例如高速 USB 2.0 On-The-Go。

The Digital Video Software Production Bundle (DVSPB) MontaVista Linux companion product is recommended for production.

DM355 Digital Video Evaluation Module includes the following components:

  • TMS320DM355 DaVinci™ processor-based development board

  • IR remote

  • Development board reference materials (gerber, schematics, BOM)

  • 2 GB NAND Flash

  • On-board Ethernet controller with application notes and schematics

  • Video capture of NTSC or PAL signals via composite video or S-video input

  • NTSC or PAL output via composite video output

  • Other features such as microphone in, headphone out, line in and line out, UART, USB 2.0 HS, 2GB NAND Flash memory and JTAG for test

  • TI eXpressDSP™ Linux-based DVSDK

  • MontaVista Pro Demonstration Tools

  • DM355 Getting Started Guide and Hardware Technical Reference

TI’s eXpressDSP Linux-based DVSDK allows system integrators to incorporate discrete software modules and combine them into a single executable output for the systems, avoiding months of tedious manual integration. By making it easy to create custom bundles of codecs for specific applications, the configuration kit makes it simple to reuse code. The DVSDK includes:

  • TI’s JPEG and HD MPEG-4 SP production codecs and G.711 codec*

  • Custom codecs that comply with TI’s eXpressDSP Digital Media (xDM) algorithm standard

  • Multimedia APIs and Codec Engine Frameworks

  • Demonstration version of MontaVista Linux Pro 4.0

  • Drivers for UART, I2C, SPI, EDMA, NAND,MMC, SD Card, USB Host/Gadget

  • Video Processing Subsystem (Display, Capture, CCD Controller, Resizer, Previewer)

  • OSS Audio (ASP), GPIO, PWM, WDTIM

  • U-boot loader
