摘要
基于Si472x单晶片数字收音机芯片和低功耗数字信号处理器TMS320VC54x系统设计和实现DSP FM收音机。收音机以TMS320VC54x为控制核心,实现全频手动和自动搜台功能。重点阐述了Silicon Laboratory公司的Si472x芯片的工作原理及特性以及收音机相关硬件电路的设计,并对软件设计流程和设计的测试结果做了简单描述,为单晶片DSP收音机的设计提供了借鉴。
Based on single chip digital FM tuner Si472x and low power consumption digital signal processor TMS320VC54x,the DSP FM radio was designed and implemented.Controlled by the TMS320VC54x,the DSP radio could realize the function of automatic tuning and manual tuning in full FM support receive band.In this paper,the principles and characteristics of single chip Si472x from Silicon Laboratory corporation and the design of DSP radio are described in detail,flow of software design and test results of radio are also demonstrated briefly,and the project can be used as the reference for the designing of DSP radio.
