第二个ByteToBcd2,在循环中每减一个10,对bcdhigh加1,而变量bcdhigh 用以累计十位数值,减到不够10以后,那就剩个位了,直接或在bcdhigh 左移四位的后面就是对应BCD的转换结果。 #include<stdio.h>typedefunsignedcharuint8_t;typedefunsignedintuint32_t;// BCD转换为二进制staticuint8_tBcd2ToByte(uint8_t...
This paper proposes two high performance binary-to-binary coded decimal (BCD) conversion algorithms for use in BCD multiplication. These algorithms are based on splitting the 7-bit binary partial product of two BCD digits into two groups, computing the contribution of each group to the equivalent...
函数的实现原理比较简单,对于第一个函数Bcd2ToByte,先对BCD数取其高四位,右移四位,再乘以10,作为十位数字;再取其第四位作为个位数字;两者作和,则为对应的二进制数转换结果。第二个ByteToBcd2,在循环中每减一个10,对bcdhigh加1,而变量bcdhigh 用以累计十位数值,减到不够10以后,那就剩个位了,直接或在bcd...
a. of or pertaining to a system of numerical notation to the base 2, in which each place of a number, expressed as 0 or 1, corresponds to a power of 2. b. of or pertaining to the digits or numbers used in binary notation. c. of or pertaining to a binary system. 3. noting...
The conversion from binary to BCD-8421-code is also performed by a fixed value circuit and may involve serial additions. Addition of BCD-8421-coded partial numbers is performed by a special adder circuit contg. a correction circuit for addition of 6. Results are transferred into the result ...
Binary-coded decimal, or BCD, is a system of representing decimal numbers in binary form. In BCD, each decimal digit is represented by a 4-bit binary code. For example, the decimal number 57 would be represented in BCD as 0101 0111. BCD is commonly used in electronic devices that display...

In the process of grouping three bits, one or two bits can be added to the left of the MSB in an integral part and/or to the right of the LSB bit of the fractional part of the binary number. Example 1: Convert (110011.011)2to ( ? )8 ...
A BCD to binary converter, particularly applicable for large numbers, employing an input level of code converter logic comprising PROM groups which provide a specially chosen initial conversion of the BCD number to be converted. Each PROM group comprises a plurality of individually programmed PROMs wh...
For example, the number 149 encoded in BCD would be 0001 0100 1001 (a binary 1, a binary 4, a binary 9). The advantage of BCD is that each binary number has to be only 4 bits in order to span the range 0–9. As the full value of the number being encoded goes beyond 9 (say...
