Design and Implementation of HDLC Protocol using VHDL technique

摘要

Data transmission for high energy physics experiments is carried out widely and efficiently using various protocols. One of its kind is High-Level Data Link Control (HDLC) protocol which is widely accepted by the International Organization for Standardization (ISO) for the data link layer of the OSI model of reference. There are uplink and downlink data paths for controlled data communication. In our system we have implemented this HDLC protocol using VHSIC High Level Descriptive Language (VHDL) and simulated the data packet transmission using the Intel-ModelSim platform to demonstrate the transmission patterns. Here we have generated data packets which are wrapped at the transmitter and decoded at the receiver end to retrieve the original data.
