On Comparison of Robust Configurable FPGA Encoders for Dependable Industrial Communication Systems

摘要

Communication technologies have experienced an explosive development. Various short-distance communication systems have been used as a way of connecting embedded electronic systems in industrial applications. Test- and error detection or correction technologies have to meet new timing challenges and requirements in modern real-time and safety-critical systems, also set by Industry 4.0. Encoders using generator polynomials with linear-feedback shift registers (LFSRs) are the key parts of communication technologies, widely used in most of today's integrated as well as field systems. This paper presents a comparison of three basic ways of implementation of adaptive encoders configurable LFSRs using conventional configurable solutions, reconfigurable LUTs in SLICEMs in Xilinx FPGAs, and also encoders using standard Xilinx partial reconfiguration.
