An Asymmetric Threshold Service Polling System Based on FPGA

Abstract

The invention relates to an FPGA implementation of an asymmetric threshold service polling system, which belongs to the field of wireless sensor network communication. The top-down design of the system is carried out by combining the schematic diagram and text input, and the FPGA built-in asynchronous fifo soft core is used to cache and send the information packets with Poisson distribution characteristics received by each site, and with the help of the distribution Frequency technology for speed matching, independent clock control for fifo memory reading and writing, to meet the processing speed requirements of the server when processing different services; the design uses threshold rules to provide services to each site, effectively overcoming the site "under complete rules" Busy” and “hunger” problems, solve the problem of frequent phase switching under limited rules, use Verilog HDL language to set up the finite state machine, control the different switching times between stations, and ensure the fairness of services between stations. The invention has flexible control and short development period, and can be widely used in various business processing occasions.

AI Technical Summary

Problems solved by technology

The traditional polling technology is becoming more and more mature, but its limitation is that the information arrival rate, service time and switching time between adjacent terminals of this technology are all the same, which greatly limits the scope of use of this technology
