[Solved] finding the first set bit in a binary number 9to5Answer

WebIf N is a number then the expression below will give the right most set bit. N & ~ (N -1) Let’s dig little deep to see how this expression will work. We know that N & ~N = 0. If we subtract 1 from the number, it will be subtracted from the right most set bit and that bit will be become 0. So if we negate the remaining number from step above ... WebDec 13, 2012 · hmm, my first thought is to (-x) & (x), which returns the rightmost set bit as a vector: 0011101000 = x 1100010111 = ~x 1100011000 = -x 0000001000 = -x&x This might be helpful if x is locally generated (the -x infers an adder which is a local structure and may cause routing bottlenecks in some cases). WebApr 17, 2024 · This will result in a number with only one set bit and the position we want. The solution will be given by log2 of the number +1. This seems a bit complex to understand let’s solve an example using this method. N= 10 , binary = 1010 2’s complement, 0101 1010 & 0101 = 0010 log2 (2) = 1 1+1 = 2 which is the given index.

In computer software and hardware, find first set (ffs) or find first one is a bit operation that, given an unsigned machine word, designates the index or position of the least significant bit set to one in the word counting from the least significant bit position. A nearly equivalent operation is count trailing zeros (ctz) or number of trailing zeros (ntz), which counts the number of zero bits following the least significant one bit. The complementary operation that finds the index or position of the …
