Associated Constants

const MAX_CHUNK_SIZE: usize

The maximum summations that can happen before accumulator overflows. This can be determined by putting the maximum word value into the algorithm and counting the number of words can be added before an overflow occurs.

const BIT_MASK: Self

Bit masking pattern to use in the reduce step. This should mask out the least significant half of the value, i.e. 0x00ff for 16 bit values

const SHIFT_AMOUNT: u16

The number of bit spaces needed to shift the most significant half of the value into the least significant half of the value. This is typically half the bit width of the type, i.e. 8 for 16 bit values
