A VLSI system to speedup the measurement of the system frequency

摘要

One of the approaches to measure the power system frequency is by the least squares method. This method involves huge computation, which is time consuming using a general purpose microprocessor-based system. In this paper, a parallel processing system to speedup the computation of frequency is introduced. The operation and the structure of the array is explained. The size and the computation time of the system are evaluated. It is shown that the proposed system speeds up the computation by at least two orders of magnitude. The system is well suited for VLSI implementation.
