现有的数字集成电路手册及教科书中,都没有给出五入五出译码器级联的一般方法。这给该电路的应用带来了极大的不便。本文所述的级联方法,无疑会给广大用户带来方便。一 BCD 码向二进制码的转换过程众所周知,十进制数向二进制数的转换可以用连除2的方法完成。将每次除2后的余数依次由低向高排列,便可得到相应的二进制数。在定点二进制数中,整个数右移一次相当于除以2一次。移出的最低位就是除以2后的余数。
None of the existing digital integrated circuit manuals and textbooks provide a general method of cascading five to five decoders. This brings great inconvenience to the application of this circuit. The concatenation method described in this article will undoubtedly bring convenience to the majority of users. A BCD code to the binary code conversion process As we all know, the decimal number to the binary number conversion can be used in addition to the 2 method to complete. Will be divided by 2 after the remainder of the order from low to high, you can get the corresponding binary number. In fixed-point binary number, the entire number of the right shift is equivalent to dividing by 2 once. Remove the lowest bit is divided by 2 after the remainder.
