摘要:

数字复分接技术是数字通信网中的一项重要技术,能将若干路低速信号合并为一路高速信号,以提高带宽利用率和数据传输效率。文中在介绍数字复接系统的基础上,采用VHDL对数字复分接系统进行建模设计和实现。并利用乒乓操作和先进先出存储器(FIFO)对复接器进行设计,利用帧同步器对数据进行分接。以QuartusII8.0为仿真软件,对设计进行仿真验证,仿真结果表明,设计实现了复接系统,便于修改电路结构,增强了设计的灵活性,且节约了系统资源。

Abstract:

An important technique in the network of communication,digital multiplexing and de-multiplexing can improve the transmission efficiency by multiplexing several low speed data flows into a high speed one.After a brief introduction to the multiplexing system,a design using VHDL for digital multiplexing and de-multiplexing is proposed.The FIFO,ping-pong operation and frame synchronization system are adopted.QuartusII8.0 is used for simulation,which shows that the design realizes the function with more flexible circuit structure and less system resource consumption.

Key words: digital multiplexing system;ping-pong operation;FIFO;FPGA
