描述

DM642评估模块是一个廉价的高性能视频&图像开发平台，用于快速开始应用开发和评估多通道、多格式数字和其他未来应用。Leveraging the high performance TMS320C64x DSP core, this development platform supports TI’s?TMS320DM642, DM641 & DM640 digital media processors.Developed in conjunction with Spectrum Digital, this PCI form factor EVM includes the necessary components to enable you to:

       

• Start application software development immediately       
  
• Understand DSP functionality for video experts       
  
• Build video, audio & internet streaming functionality into existing designs       
  
• Simplify overall system design       
  
• Differentiate your product with cutting edge software       
  
• Design for flexibility to respond to evolving standards
  

Supported by award winning eXpressDSP host tools and target software, users have the unique ability to quickly and easily integrate eXpressDSP-compliant?algorithms?from over one hundred TI third parties into the included starterware to accelerate completion of your evaluation and development of digital media solutions.For users who require a more comprehensive development kit including a complete set ofeXpressDSP?host development tools and target software, an?XDS560?high speed advanced emulator, camera and cables, please see the?DM64x Digital Media Developer’s Kit?for more information.The software included with the EVM allows you to seamlessly jump-start development. The Device Driver Kit (DDK) provides customers with ready to use?DSP/BIOS?device drivers for TI DSP peripherals and working examples to develop your own device drivers.Initial low-level design decisions are eliminated when using the eXpressDSP?Reference Framework5 (RF5) because it provides a getting started solution in the early stages of application development. This easy-to-use source code is common to many applications. RF5 is designed to handle anywhere from 1 to 100+ channels of data, and from 1 to 100+ different algorithms. It makes maximal use of several of the advanced DSP/BIOS capabilities such as the task module (TSK) and semaphore module (SEM). This allows truly dynamic, multi-channel, multi-rate operation where any channel can block any other channel. Streams like audio and video can easily be mixed together.Source code is available for Video Application demos for Composite/S-Video In/Out, Capture/Display pass-thru, On-Screen Display (OSD) and Audio Loopback, while object code libraries are included for Streaming Media executable demos such as Video Loopback (H.263, MPEG-2 video and JPEG), TCP/IP Networking stack (Client Configuration), Network camera and Audio Loopback (G.729).The full contents of the kit include:
