Because of the reuse of some building blocks , such as adders and registers in fft processor , and the regularity of the circuit structure , the test scheme can be implemented at ? speed and in parallel without circuit performance degradation , and with minimal additional hardware and area overhead 由于处理器中一些加法器、寄存器的再利用，以及电路结构的规则性，因而只需最少的额外硬件、面积开销即可真速、并行地实施该测试方案而不会降低电路性能。
Collaborative optimization ( co ) is one of very promising multidisciplinary design optimization ( mdo ) methods . this method dissolve complex system analysis and is able to conduct the analysis of disciplines in parallel via disciplinary decompose . furthermore , the architecture of co is a natural fit to the current aircraft design organizations 协同优化方法是多学科设计优化中比较优秀的一种方法，它消除了复杂的系统分析，使各个子系统能够并行地进行分析和优化，而且其算法结构与现有的飞机设计专业分工组织形式相吻合。
So , more and more distributed applications adopt redundant servers : on one hand , the system availability could be improved through adding the redundancy of data and computation ; on the other hand , user requests are processed on several servers in parallel , so the system performance could be advanced by this means 为此，许多分布式应用采用了冗余服务技术：一方面，通过增加数据和计算的冗余度，提高了系统的可用性；另一方面，多个服务器并行地响应用户请求，提高了系统的性能。
The theory and methodology of product life cycle design ( lcd ) , originated from the idea of concurrent engineering ( ce ) , can fulfilled the products design considering all related issues of every phases of product whole life cycle in early design process . by using the lcd methods ， the products can be of good manufacturability , assemblablity , recycleability , serviceability , economic and environment - friendliness , et al 产品生命周期设计( lcd )理论和方法源于并行工程( ce )的思想，在设计早期阶段就并行地考虑产品的整个生命周期过程中各个阶段的因素，使设计出来的产品具有良好的可装配性能、可制造性能、服务性能、可回收性能以及环境性能等。
