Struct ScalarReducePipe 

pub struct ScalarReducePipe { /* private fields */ }

Fifty-seven-stage, initiation-interval-one reduction modulo l.

Three fixed-constant folds remove bits above bit 251. Six final registered add/subtract stages canonicalize the result. Every loop count and data path is independent of the input value.

Trait Implementations

impl Clone for ScalarReducePipe

fn clone(&self) -> ScalarReducePipe

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ScalarReducePipe

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

Formats the value using the given formatter.

impl Default for ScalarReducePipe

fn default() -> Self

Returns the “default value” for a type.

impl Synchronous for ScalarReducePipe

type S = (<ScalarReducePipe as SynchronousDQ>::Q, <ConstQMulPipe as Synchronous>::S, <ConstQMulPipe as Synchronous>::S, <ConstQMulPipe as Synchronous>::S, <FoldSideDelay as Synchronous>::S, <FoldSideDelay as Synchronous>::S, <FoldSideDelay as Synchronous>::S, <DFF<FinalReduceRegs> as Synchronous>::S)

The simulation state type. This type is used to represent the internal state of the circuit during simulation. It must be PartialEq and Clone. It holds whatever state is needed to compute the output of the circuit given it’s input. This state is typically auto-derived by the Synchronous derive macro, and it’s typically a struct containing the states of all the subcircuits, along with their last know outputs.

fn init(&self) -> Self::S

Initialize the simulation state. This method returns the initial state of the circuit for simulation. This is typically auto-derived by the Synchronous derive macro, and it typically initializes the states of all the subcircuits to their initial states.

fn children( &self, parent_scope: &ScopedName, ) -> impl Iterator<Item = Result<Descriptor<SyncKind>, RHDLError>>

Iterate over the child circuits of this circuit.

fn sim( &self, clock_reset: ClockReset, input: <Self as SynchronousIO>::I, state: &mut Self::S, ) -> <Self as SynchronousIO>::O

Simulate the circuit given it’s input, clock reset, and current state.

fn descriptor( &self, scoped_name: ScopedName, ) -> Result<Descriptor<SyncKind>, RHDLError>

Provides run time reflection of the circuit.

impl SynchronousDQ for ScalarReducePipe

type Q = ScalarReducePipeQ

The type of the internal data output from the children of the circuit.

type D = ScalarReducePipeD

The type of the internal data input to the children of the circuit.

impl SynchronousIO for ScalarReducePipe

type I = ScalarReducePipeIn

The type of the input to the circuit.

type O = ScalarReducePipeOut

The type of the output from the circuit.

type Kernel = scalar_reduce_pipe_kernel

The type of the kernel function used to compute the output and feedback. The kernel function must be a synthesizable function that takes a clock and reset signal, the input signal, and the feedback signal Q, and produces the output signal and feedback signal D.
