In real-time systems the computer must "keep up," processing all data at high speeds in order to be effective.
在及时的系统计算机必须“跟上，”以高速度处理所有的数据以便有效。

Early computer operation speed is low, the time for scientific computing, and data processing impact is not quite, can not adapt to the requirements of real-time control machine tools.
早期计算机运算速度低，对当时的科学计算和数据处理影响还不大，不能适应机床实时控制的要求。

Both the design method and implementation of a Real-time Data Processing System based on multi-channel and multi-computer are presented in this paper.
