Abstract :
In this paper, an overview of optimization methods for signal processing based on general purpose processor (GPP) is presented. It includes look-up-table (LUT), Single Instruction Multiple Data (SIMD) and Intel Integrated Performance Primitives (Intel IPP) Library. Utilizing these methods, the physical layer process modules in TD-LTE system can achieve huge benefits in real-time performance. The advantages and drawbacks of these optimization methods are analyzed and discussed, which offers a reference for realizing real-time communication systems on GPP.
