VIRTEX系列FPGA在SDH中实现片上系统

Application of VIRTEX FPGA Series in System-on-a-chip for SDH

介绍了VIRTEX系列现场可编程门阵列 (FPGA)作为系统级可编程器件的结构特点和在光同步数字传送网 (SDH)产品中开发片上系统 (SOC)的高效应用。VIRTEX系列FPGA系统集成度高达 10 0万门 ,存贮器为三级存贮结构 ,四个独立的锁相环电路用于内外时钟同步 ,接口采用选择接口技术。成功地用XCV10 0型FPGA开发了 8× 8路的VC - 4数据的数字交叉连接(DXC)芯片。

The design feature of a field programmable gate array (FPGA) of VIRTEX series used as a systemic programmable device is introduced.It can be effectively used for the development of system-on-a-chip (SOC) for SDH products.Using selected I/O technology,VIRTEX FPGA series range up to one million gates,with three levels of memory hierarchy and four fully digital delay locked loops for internal and external clock synchronization.By using model XCV100 FPGA,an 8×8 VC-4 DXC chip has been successfully developed.
