verilog binary to decimal and hexadecimal

If so, the value is increased by 6 to adjust it to within 10, and the carry is shifted to the upper 4-bit BCD code. At this time, it should be judged whether the value is greater than or equal to 10. Since the entire calculation is implemented in successive shifts, ABCDE is obtained after shifting one bit (E is from low displacement and its value is either 0 or 1).

Suppose ABCD is a 4-digit binary number (possibly ones, 10 or 100 bits, etc.), adjusts it to BCD code. The principle of hexadecimal number to BCD number conversion.Note: Do not add 3 when moving to the last digit, put the operation result directly

Shift the hexadecimal number by one to the left, and put the removed part into the defined variable, and judge whether the units of ten thousand, thousand, hundred, ten, and one are greater than or equal to 5, and if so, add the corresponding bit to 3 until the 16-bit shift is completed, and the corresponding result is obtained.First define five four-digit binary units: ten thousand, thousand, hundred, ten, and one to accommodate calculation results The maximum value can be expressed as 65535. Suppose you want to convert the 16-digit binary value (4-digit hexadecimal) to decimal. Set the maximum decimal value of the expression.Bitwise operations (specifically, shift bits and plus 3 here).When the hexadecimal number is reduced to 0, the BCD counter Just gets with the same value to display. At the same time, the appropriate BCD code decimal counter is designed to increment. Under the control of the synchronous clock, the hexadecimal number is decremented by 1 until it is reduced to 0. Human eyes recognition is relatively slow, so the display from hexadecimal to decimal does not need to be too fast. Since the hexadecimal display is not intuitive, decimal display is more widely used in real life. 7.3 Experiment 7.2.1 Introduction to the principle of hexadecimal number to BCD code Learn to convert hexadecimal numbers to BCD code (hex_to_bcd)Ĭombined with experiment 6, display the results of the operation to the segment display.
