| Abstract: | This paper provides the project of three paths sinewave signal generator special-purpose chip based on open source idea and SOPC technology. The generator uses the 32 bits open source soft IP core CPU OR1200 and open source soft IP core DDS. The frequency and phase can preset and regulate. The sinewave signal generator special-purpose chip realizes based on OR1200 curing special program, transfers the control data through UART, and controls the system to generator three paths sinewave simultaneously. The fr... |
