Bitscan forward

WebThe mask separation is cheaper than the bit isolation due to the x86 lea instruction, performing the decrement of a source register into another target register, not affecting processor flags. This is a 32-bit bitscan forward routine: WebIn 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 …
