程序优化 meaning in English
program optimization
Examples
- By the analysis , it was found out that the key control factor determined the speed limit and storage energy was the poor transverse tension strength of the composites . therefore , if only fibers of high longitudinal tension strengths were used in the rim , high rotate speed and high energy storage density of flywheel rotor would not be achieved
经过理论推导及程序优化比较，发现，影响飞轮转子极限转速和储能量的主要控制因素，恰好是其复合材料轮环较为薄弱的横向拉伸强度，因此单纯地通过采用高纵向拉伸强度的高强碳纤材料来制造飞轮转子，并不能得到期望的高转速和储能密度。 - If you put extraneous code y into your benchmark , you re now measuring the performance of x y , introducing noise into your measurement of x , and worse , the presence of y changes how the jit will optimize x . writing a good microbenchmark means finding that elusive balance between not enough filler and dataflow dependency to prevent the compiler from optimizing away your entire program , and so much filler that what you re trying to measure gets lost in the noise
如果在基准中加入无关的代码y ，那么现在度量的就是x + y的性能，更糟糕的是，由于y的存在，现在jit优化x的方式又发生了变化。如果没有足够的额外填充物和数据流依赖，编译器可能会将整个程序优化至无形，但是如果填充物太多，那么真正需要度量的东西又会迷失在噪音当中，因此要编写一个良好的微基准，就意味着要抓住二者之间微妙的平衡。 - In china , the relic industry began to realise the importance of informationization recently , now facing the challenge of the new century it needs informationization , so relic bureau of shanxi province and beijing taijihuaqing information system ltd developed cooperatedly the relic information colligation platform . basing designing and developing that platform , the question for study has made some practice and study on some facts , such as software unified process , visualized modeling , optimizing program , the technique data mining and data warehouse
我国的文物行业信息化起步比较晚，面对新世纪的挑战，迫切需要走上信息化的道路。为此，山西省文物局、北京太极华青信息系统有限公司联合开发了山西文物综合信息平台。本课题在设计与开发本系统的基础上，从统一软件开发过程、系统的可视化建模、程序优化技术、数据挖掘技术、数据仓库技术等几个方面做了相关的研究与实践。 - Finally , basing on the above theory research and the existing hardware scheme , the optimization probabilities is discussed among the layers of the standard entrails , arithmetic promotions and program optimizations . the optimizations are carried out in the software simulation circumstance , and obtain a notable effect , which boosts the coding speed by 60 % with the same image quality , showing an applying prospect
最后,在以上的理论研究基础上,结合现有的硬件方案,从标准内部、算法改良和程序优化等多个层面上探讨了对视频编解码系统的优化可能,并在软件仿真的环境下付诸于实践,取得了明显的效果,在保证图像质量的前提下,将编码速度提高了约60 % ,显示出了一定的实际应用前景。
