Design of Digital Three-Phase SPWM Signal Generation System Based On SoC

摘要

With the developing of the integrated circuit design and fabrication technology gradually,system-on-chip (SoC) technology has been widely used because of its high performance such as small size,low power consumption and so on. This paper describes a digital three-phase SPWM signal generation SoC based on OpenRISC1200,a 32-bit RISC processor core. The system integrates parameter controlling,dispalying and signal generating on one chip,and therefore improving many inconveniences from its original separate controling. In this SoC design,software/hardware Co-design method is adopted,and system level verification based on Cyclone II FPGA (EP2C35F672) of Altera is carried out. The test results show that the design achives the design specification perfectly.
