Web16 Bit Double Dabbler VHDL module.. or just an integer to binary-coded decimal converter. This VHDL module executes the double dabble algorithm to turn a 16 bit unsigned integer into a binary-coded decimal.The output consists of a vector of 20 bits, where each subvector of 4 bits represent a decimal number (0-9).

WebIn the 1960s, the term double dabble was also used for the mental algorithm used by programmers to convert a binary number to decimal. It is performed by reading the binary number from left to right, doubling if the next bit is zero, and doubling and adding one if the next bit is one.
