基于Linux平台的DSP编程性能优化
Performance optimization of DSP programming based on Linux platfrom
摘要
Abstract
At present, the sustainable development of DSP chip has made it been applied in many fields maturely since 1980. Inpractical industrial applications, a good algorithm always tends to go through lots of system optimization to meet the ever⁃increasingperformance requirements. Performance analysis tool gprof of Linux platform is used to analyze the overall structure of the programfirstly, and then based on the analysis result more focused and targeted optimization is implemented. The optimization methodsinclude complier option optimization, instrinsic functions optimization, loop optimization and storage space allocation optimization.In this paper, MELP(Mixed⁃Excitation Linear Prediction) speech codec is taken as an example to illustrate. As it can be seen fromthe experimental results, this kind of optimization method has higher efficiency and better effects compared with general optimization.关键词
