基于FPGA的VC12交叉汇聚系统研究
Research on VC12 crossover and convergence based on FPGA
摘要
Abstract
In order to realize the extraction of VC12 particles in SDH communication,this pape uses FPGA to achieve a strict non blocking all intersection of granularity of VC 12 in ITU-T G.707 protocol.Cross capacity is 15G with implementation of 16 STM16 inputs to the 4 STM16 output data convergence cross supporting VC 12 level broadcast function.It completes overhead interpretation and generation,pointer interpretation and generation,frame search and generation and others in SDH.It also do monitoring and statistics of data transmission performance with alarm and interrupt reporting functions.关键词
