Bitec Cyclone III EP3C129视频开发方案

Altera公司的Cyclone III FPGA是理想的视频处理平台,具有大量的乘法器,低功耗和M9K存储器区块. Bitec公司的Cyclone III视频开发套件采用Altera的EP3C129器件和连个HSMC视频接口卡以及一组IP核,能提供各种接口标准,包括高达HD分辨率的数字和模拟.本文介绍了采用Altera的EP3C129的视频开发的特性和详细电路以及视频DVI开发板的电路图.

Alteras Cyclone III device is an ideal video processing platform given the large number of multipliers, low power and M9K memory blocks.

Bitec have made available a cost effective kit targeted at Video processing development using a Cyclone III device for the core processing. The kit contains the Cyclone III FPGA Development Kit which utilizes an EP3C129 device and two HSMC video interface cards together with a collection of IP cores and reference designs. The kit provides a variety of video interface standards including both digital and analogue up to HD resolutions.

The Bitec Cyclone III Video Development Kit provides an integrated solution for developers wishing to utilize the Cyclone III device for video applications. With a growing collection of reference designs based on the Altera VIP Suite, development time is reduced to the minimum.

With two independent 32-bit DDR2 memory interfaces, the Cyclone III VDK is able to tackle the most challenging High Definition video applications.
