Pipeline stages of ParallelFieldMulEngine.

Variants

Idle

Waiting for a field request.

MultiplyProducts

Register all split 26-by-13 limb products.

MultiplyCombine

Combine low and high split products.

MultiplyScalePrepare

Prepare factor-2 and wrapped-term scaling.

MultiplyScale

Apply alternating-radix and factor-19 scaling.

ReducePairs

First pairwise level of each ten-term adder tree.

ReduceQuads

Second adder-tree level.

ReduceEights

Third adder-tree level.

ReduceFinal

Add the final two terms for each output limb.

AddSubtract

Perform limb-wise add or biased subtract instead of multiplication.

CarryQuads

Carry-reduce the first groups of four limbs.

CarryLast

Carry-reduce the remaining high limbs.

CarryWrapScale

Scale the bit-255 wrap carry by 19.

CarryWrapFinalize

Add the wrap carry to limb zero and restore low-limb bounds.

Done

Present the completed field result.

Trait Implementations

impl Clone for ParallelFieldMulState

fn clone(&self) -> ParallelFieldMulState

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ParallelFieldMulState

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Default for ParallelFieldMulState

fn default() -> ParallelFieldMulState

Returns the “default value” for a type.

impl Digital for ParallelFieldMulState

const BITS: usize

Associated constant that gives the total number of bits needed to represent the value.

fn static_kind() -> Kind

Returns the [Kind] (run time type descriptor) of the value as a static method

fn bin(self) -> Box<[BitX]>

Returns the binary representation of the value as a vector of [BitX].

fn discriminant(self) -> TypedBits

Returns the discriminant of the value as a [TypedBits].

fn variant_kind(self) -> Kind

Returns the [Kind] of the variant if the value is an enum with variants.

fn dont_care() -> ParallelFieldMulState

Returns a “don’t care” value for the type.

fn bits() -> usize

Returns the number of bits needed to represent the value.

fn kind(&self) -> Kind

Returns the [Kind] (run time type descriptor) of the value.

fn typed_bits(self) -> TypedBits

Returns the value as a [TypedBits], which includes both the bits and the kind.

fn binary_string(self) -> String

Returns the binary representation of the value as a string of ‘0’, ‘1’, and ‘X’.

impl PartialEq for ParallelFieldMulState

fn eq(&self, other: &ParallelFieldMulState) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
