摘要:

智能仪器是计算机技术与测量技术以及仪器仪表技术相结合的产物。它具有传

统仪器无法比拟的优点。在精度,可靠性方面都有了本质性的改变。仪器硬件都趋于采

用嵌入式系统、片上系统等结构。电子计算器是能进行数学运算的手持机器,拥有集成

电路芯片,采用 来实现电子计算器的各个功能。该电子计算器由按键输入的数值显

示在7段数码管上,但只限4位数;按加、减、乘、除键时,第一次输入的值被存放在

缓冲区中,当做被加、减、乘、除数,且加、减、乘、除相对的运算指示灯会亮;接着

输入一个数,之后若是按下“=”键,则此加、减、乘、除数被存放于另一个缓冲区中,

与刚才输入的数做运算,且相对应的运算指示灯熄灭;运算结果显示在7段数码管上。

Abstract:

Intelligent instrument is the computer technology and measurement

technology and instrumentation technology combined with the product. It has the

incomparable advantage of traditional instruments. In the accuracy, reliability are all

essential changes. Instrument hardware are tending to use embedded system,

system on chip structure. An electronic calculator is able to perform mathematical

operations on handheld machine, has integrated circuit chip, used to realize each

function of the electronic calculator. The electronic calculator from the key input

values displayed in the7digital tube, but only4 digits; according to plus or minus,

multiplication, addition to the key, the first input value is stored in the buffer, as is plus

or minus, multiplication, addition, subtraction, division, and, in addition to take relative

operation indicator light; and then enter a number, then press" if = " button, the plus,

minus, multiplication, the divisor is stored in a buffer, and just the number of inputs to

do arithmetic, and the corresponding operation indication lamp is extinguished;

calculation results in the7 digital tube on.

Key words:

Intelligent instrument system on chip electronic calculator

integrated circuit chip buffer
