Descripción
Sumario:Discrete microprocessor-based equipment is a typical synchronization system on the market which implements the most critical features of the synchronization protocols in hardware and the synchronization algorithms in software. In this paper, a new clock discipline algorithm for hardware implementation is presented, allowing for full hardware implementation of synchronization systems. Measurements on field-programmable gate array prototypes show a fast convergence time (below 10 s) and a high accuracy (1 μs) for typical configuration parameters.
