摘要
针对国内对于专用通信引擎的研究空缺,实现了一种支持多协议的可配置通信引擎设计,并以典型的数据链路层协议——高级数据链路控制(High 1evel Data Link Control,HDLC)协议的引擎块实现为例,采用System Verilog搭建仿真平台,通过C语言编写测试case,以回环验证的方式保证设计正确性。可配置引擎块以自研RSIC核为核心,采用AHB总线互连,内部集成HDLC、UART等通信协议以及DMA、TDM、GPIO等通用外设,实现通信协议的处理及数据传输,有助于解放处理器负载,提高数据处理效率,同时将HDLC与可配置通信引擎相结合,解决了多路信号的HDLC对处理器资源的占用率高等问题。
In this paper,aiming at the research vacancy of dedicated communication engine in China,a design of configurable communication engine supporting multiple protocols is implemented.Taking the typical data link layer protocol,the engine block implementation of high-level data link control(HDLC)protocol,as an example,the simulation platform is built by System Verilog,and the test case is written in C language to ensure the correctness of the design by loop verification.The configurable engine block takes the self-developed RSIC core as the core,adopts AHB bus interconnection,integrates communication protocols such as HDLC and UART and general peripherals such as DMA,TDM and GPIO,etc.,and realizes the processing of communication protocols and data transmission,which helps to free the processor load and improve the data processing efficiency.At the same time,the combination of HDLC and configurable communication engine solves the problem of high utilization rate of processor resources by HDLC with multi-channel signals.
