军用计算系统已达到了计算机性能的极限,即使对运算速度和可靠性要求不很高的非军事应用也是如此。这一点在信号处理(包括雷达、声纳和语言处理)中尤为突出。 在信号处理中,系统的输入是一组由复杂波形组成的连续信号流。完成这项工作的系统需要专用计算机。该系统成本高达数百万英镑,且体积太大,不能用于战术导弹中, Military computing systems have reached the limits of computer performance, even for non-military applications where computing speed and reliability are not critical. This is especially true in signal processing (including radar, sonar and speech processing). In signal processing, the system’s input is a continuous stream of signals consisting of complex waveforms. The system to do this requires a dedicated computer. The system costs millions of pounds and is too bulky to be used in tactical missiles.
