WebModulo operations might be implemented such that a division with a remainder is calculated each time. For special cases, on some hardware, faster alternatives exist. For example, the modulo of powers of 2 can alternatively be expressed as a bitwise AND operation (assuming x is a positive integer, or using a non-truncating definition): WebMay 8, 2015 · Modulo can be easily translated into a bitwise ANDif the divisor is a power of two.

You are confusing operations on a single bit with operations on a byte,or word. (Multiple bits) A single bit represents either 0 or 1 depending on its value. If you add two bits, and ignore the carry, you are adding "mod2". 0+0 = 0 0+1 = 1 1+0 = 1 1+1 overflows, or carries, and you have 0. this is exactly the same as XOR. optical illusion bottle

WebI've heard you can use the logical AND to turn moduli of the form (2^n) into bitwise functions of the form ((2^n)-1). I.E. You could AND the ARRAY_SIZE with '7' (if doing 8 unrolls) and get the remainder. I tried simply doing: efficientRemainder = ARRAY_SIZE && 7 (and similar), but this is quite wrong. Or the source is incorrect. WebApr 3, 2024 · The usage of bitwise operations mainly fall into 2 categories: Data chopping/sewing : Example, a floating point value is an assemblage of 3 parts packed in a binary value, accessing to individual parts require some chopping.
