WebI know this is a bit of a necro-comment, but some of those operations are not necessary. For example, in addition, the lower bits of the result do not depend on the higher ones, so you don't need to do the & 0xff for every byte, you can do it once in the end without changing the result. Casting to byte even makes the last & 0xff redundant. – harold WebThen it assembles the new parity values into the binary number in order of r position (r8, r4, r2, r1).

WebIn the case of even parity, for a given set of bits, the bits whose value is 1 are counted. If that count is odd, the parity bit value is set to 1, making the total count of occurrences of 1s in the whole set (including the parity bit) an even number. If the count of 1s in a given set of bits is already even, the parity bit's value is 0.
