FPGA在程控数字交换机中的应用研究

Application of FPGA technology to digital programmable control exchange

针对现有程控数字交换机大多采用传统搭积木式(即用器件搭成电路板)的设计方法,提出用现场可编程门阵列(FPGA)技术设计的新思路,并通过VHDL语言设计给出了仿真结果,结果表明,用FPGA设计的数字程控交换模块具有硬件结构简单、性能良好、功能易于升级等优点.

In allusion to the traditional method used to design programmable control exchanger by building blocks, a new design method of using field programmable gate array (FPGA) is given. The numerical programmable exchange models are designed by FPGA and VHDL. The simulation result indicates that the hardware architecture of models is simple and the performance is excellent, and the function can be easily updated.
