摘要

本文介绍了一种可扩展的共享缓冲ATM交换机的体系结构和FPGA(现场可编程门阵列)的实现。所提出的ATM交换机具有一个二维子内存块阵列作为共享缓冲区。我们可以在不改变电路的情况下,通过增加数组的大小来扩大缓冲容量。设计了4/spl times/4 ATM交换机的原型开关,该开关具有32个16字节单元的共享缓冲区,并使用FPGA实现了该开关,以验证其功能。设计的试验台工作频率为40mhz。

FPGA implementation of a scalable shared buffer ATM switch
This paper describes the architecture of a scalable shared buffer ATM switch and FPGA (field programmable gate array) implementation. The proposed ATM switch has a 2-D array of sub-memory blocks as a shared buffer. We can enlarge the buffer capacity by increasing the array size without any change of circuit. The prototype switch has been designed for a 4/spl times/4 ATM switch which has a shared buffer for 32 16-byte cells and implemented using FPGA to verify its function. The operating frequency of the designed test-bed is 40 MHz.
