一种基于FPGA的基带64×64数据分配矩阵设计

Design of baseband 64×64 data distribution matrix based on FPGA

数字分配矩阵网络及矩阵开关是自动测试系统的重要组成部分,担负着控制信号流的任务,常用于卫星/移动/电信E1/T1信号程控分配调度。采用FPGA作为实现控制逻辑的核心部件,介绍了上位机的软件设计思路和FPGA的内部编程实现及仿真。该方案具有规模大、成本低、高速等特点,可广泛应用于大规模基带数字系统测试及信号程控分配调度中。

Digital distribution matrix net and matrix switch are important parts of automatic testing system, which controls the signal flow, and commonly used in the satellite, mobile, Telecom E1 or T1 signal program-controlled dispatching. FPGA is used as the core component of the control logic. The software design ideas of the upper computer, and the internal programming implementation and simulation of FPGA are introduced. The scheme has the characteristics of large scale, low cost, high speed. It can be widely used in large-scale digital baseband system testing and signal program-controlled dispatching.
