摘要
排队策略与缓冲技术是交换矩阵设计的核心,同时也是交换矩阵时延产生的主要因素。共享缓冲对于减少数据缓冲容量极为重要,是目前大容量交换的基础。采用了Crossbar思想的零缓冲技术是时分交换与空分交换的融合,通过VHDL语言编程,提出了适合工程的小容量交换矩阵设计思路,并在工程中得到了检验。
The queue strategy and buffer technique are the core of switch matrix design and they are also the main factors in time delay generation of switch matrix. Shared buffer, which is the base of great capacity switch, is of extreme importance to reduce data buffer capacity. The 0 buffer capacity technique adopting Crossbar idea is the amalgamation of time division and space division. The paper offers small capacity switch matrix design method suitable to the engineering by using VHDL language, which is also verified in the engineering.
