Configurable communication engine design supporting multiple protocols

Abstract： 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.
