一种新型的128路多通道HDLC引擎设计

Design for Multi-channel Communication Engine Structure

文章讨论了在SoC通讯处理器芯片中的多通道通讯引擎的结构。该通讯处理器中包括了能处理不同通讯协议的微引擎,多通道微引擎是其中的一个,其实现采用了新的体系结构,4个32路通道独立运作,可支持多种工作模式,全部复用可以处理高达128路通道。每个32路通道内部采用了可重用的结构,分为协议处理为主的位处理器和数据处理为主的字节处理器两大部分。该设计通过了FPGA验证。

This paper describes the design of new multi-channel communication processor engine structure of which can support up to 128 channels. MCC engine is composed of four 32-channel groups which can work independent. Every group can works together with another group by time-slot-assigner decoding and register setting.
