【摘要】 系统级封装（System in a Package,SiP）已成为后摩尔时代缩小电子器件体积、提高集成度的重要技术路线，是未来电子设备多功能化和小型化的重要依托。针对信号处理系统小型化、高性能的要求，采用SiP技术设计了一种高性能信号处理电路。该SiP电路集成了多种裸芯，包括DSP、NOR Flash、DDR3和千兆网PHY芯片，实现了一种通用的信号处理核心模块的小型化，相比于传统板级电路在同样的功能和性能的条件下，该SiP电路的体积和重量更小。更多还原

【Abstract】 System in a Package(SiP) has become an important technical route to reduce the volume of electronic devices and improve the integration degree in the post Moore era. It is an important support for the multi-function and miniaturization of electronic equipment in the future. Aiming at the requirements of miniaturization and high performance of the signal processing system, this paper uses SiP technology to design a high-performance signal processing circuit. The SiP circuit integrates a variety of bare cores, including DSP, NOR Flash, DDR3 and gigabit network PHY chips, realizing the miniaturization of a general signal processing core module. Compared with the traditional board level circuit, the SiP circuit is smaller in size and weight under the same conditions of function and performance.更多还原
