采用16位微处理器代替8位微处理器,可以把个人计算机从智能终端水平提高到工业实时控制领域。用 BASIC 语言写成一套工程单位变换的试验程序,在慢的8位机上运行约需700秒,而在快速的16位机上运行仅需4秒。同时长的字长可以增加访问存储器的能力和运算的精确性。因而,现在个人计算机在存储能力方面的限制已有缓和,今后要着力使它使用起来更容易。 Using 16-bit microprocessor instead of 8-bit microprocessor, you can personal computers from the level of intelligent terminals to real-time industrial control field. Writing a set of engineering unit transformation tests in BASIC language takes about 700 seconds on a slow 8-bit machine and just 4 seconds on a fast 16-bit machine. At the same time, a long word length can increase the memory access and accuracy of the operation. Thus, personal computers have now been easing their limits on storage capacity and will strive to make it easier to use in the future.
