摘要:

提出一种高速、低功耗路由查找引擎结构ISCP TCAM(ImprovedStage ControlPipeline TernaryContentAddressableMemory),这种结构不但具有传统内容可寻址寄存器(TCAM)管理简单、 更新容易、查找快速等优点,而且功耗要比同等容量的TCAM小得多。同时为进一步评估其性能利 用ALTERA公司的逻辑可编程门阵列(FPGA)实现了这一结构。该结构在低功耗高速路由查找引擎 的设计中是一个较好的选择。

关键词: TCAM, ISCP-TCAM, 路由表查找, 低功耗

Abstract:

ropose the ISCP-TCAM (Improved Stage-Control Pipeline Ternary Content Addressable Memory),a high speed power-efficient routing table search architecture.This architecture not only has the merits of easy managing and updating of conventional Ternary Content Addressable Memory(TCAM),but also power-efficient compare with the TCAM with the same size.In order to evaluate it’s performance,we implement it with FPGA of ALTERA company.It is a good selection in the design of high speed power-efficient routing table search engine.

Key words: TCAM, ISCP-TCAM, routing table search, power-efficient
