Binary gray codes with long bit runs
WebSep 28, 2008 · For every n ⩾ 1, n ≠ 3, there exists a Gray code of length n which induces the complete graph K n. In Example 3.2 we constructed a 7-bit Gray code inducing the complete graph K 7. We mark the transitions s 2 = 2, s 4 = 4, s 6 = 1, s 9 = 3, s 22 = 5, s 32 = 6, s 41 = 7 in S ¯ ( 7). WebThe Black and White of Gray Code. Gray code (named after it's inventor Frank Gray) is a sequence of binary numbers where only one bit changes at a time. Marching through the integer sequence then only requires flipping one bit at a time which in certain applications drastically reduces any errors.

WebDec 19, 2016 · One way to do this would be to compute the Gray codes in order and for each consecutive pair (x, y) compute (x XOR y) to identify which bit changed and then take the integer log base 2 of (x XOR y). However I need the iteration to be as fast as possible and my interest will be in 30-40 bit Gray codes. Is there an efficient way to do this? … WebMay 5, 2024 · There are multiple different ways to make a Gray code (only one bit flips between consecutive values). AFAIK, x ^ (x>>1) is the cheapest to compute from binary, but it's not impossible there could be something you could do with only 2 instructions, given input in a register.
