在数据采集系统中,经常要把所得到的定点格式的补码或偏移码转换成浮点数,以便参加测控运算.本文给出了用80X87数字协处理器进行上述工作的思想和方法.
In the data acquisition system, the complement or offset code of the fixed-point format is often converted into floating-point numbers in order to participate in the measurement and control operations.This paper presents the ideas and methods of using the 80X87 digital coprocessor to do the above work.
