当数据从一个设备传送到另一个设备时,用于补偿数据流速率差或事件发生时间差的一种例行程序或存储器。
A routine or storage used to compensate for a difference in rate of flow of data, or time of occurrence of events, when transferring data from one device to another.
而现有的并行程序绝大多数是依赖机器的,因此并行程序的可移植性差且难于预测性能。
While present parallel programs mostly machine dependent, so the transportability of parallel programs are very poor and it is very difficult to predict the program performance.
通过对原串行程序进行分析与测试,确定了以曲率计算、第一次差分计算和第二次差分计算等为并行化的重点。
Through the analysis and test of original serial program system, curvature computing and first difference, second difference etc. are defined as key objects.
一种是利用差累积向量,另一种是利用持续行程编码。
One is based on the accumulative difference vector and the other is based on the use of run-length encoding.
该策略根据油门开度和发动机转速与离合器输出轴转速差,并通过控制离合器驱动机构的行程增量,满足驾驶员平稳、快捷的要求,同时具有所需输入信号少的特点。
The strategy controls the rotation speed difference between engine and the clutch drive mechanism distance increment. It makes it possible to satisfy the requirement of controlling smoothly and fast.
