美国今年年底预计将研制成一台极小的微型计算机,供空中导航系统使用。这台机器是根据已经运行的阿持拉斯(Atlas)微型导航计算设计而成的第三台计算机。与前两台比较,它的特点是:体积、重量、消耗功率都小;存贮量并没有减少、速度却有显著提高。其主要数据如下:重量为15磅;体积是0.3立方英尺;消耗功率为50瓦;存贮量2,300个字;字长27位;重复频率为1兆周;加法时间、乘法时间各为0.027及0.135毫秒(原文误为0.135微秒)。
The United States is expected to develop a very small microcomputer by the end of this year for use in air navigation systems. The machine is a third computer designed on the basis of already running Atlas mini-navigation calculations. Compared with the previous two, it features: volume, weight, power consumption are small; storage capacity did not reduce the speed has significantly improved. The main data are as follows: a weight of 15 pounds; a volume of 0.3 cubic feet; a power consumption of 50 watts; a storage capacity of 2,300 words; a word length of 27 bits; a repetition frequency of 1 trillion weeks; addition times, multiplication times of 0.027 and 0.135 ms (the original error was 0.135 microseconds).
