Design and Implementation of Digital Switching Chip Based on FPGA

Abstract

Digital switching chips play a key role in program-controlled digital switches. In order to overcome the changes in the requirements of program-controlled digital switches, when the original digital proprietary chips no longer meet the requirements, this paper studies the role and composition of digital switching chips, and proposes a method of using FPGA technology to design digital switching chips. The general-purpose chip is used to replace the proprietary digital exchange chip, the general-purpose FPGA chip is used to replace the dedicated digital exchange chip, and the software design is used to replace the hardware design. The experimental results show that the designed digital switching chip can meet the needs of program-controlled digital switches and adapt to the changes in the technical indicators of program-controlled digital switches.
