Struct ScalableSignCore 

pub struct ScalableSignCore<const NFB: usize, const NSHA: usize, const NSC: usize, const NCP: usize, const CB: usize, const SH: usize>
where
    W<CB>: BitWidth,
{ /* private fields */ }

Resource-scalable cached-key Ed25519 signer with 2^CB sign contexts (CB <= 11; CTX_BITS for the throughput profiles).

• NFB: fixed-base machines (32 contexts each).
• NSHA: SHA-512 rings (still instantiated when SH = 1, but unused).
• NSC: scalar rings.
• NCP: batch-compress stages, 0 (fused: each fixed-base machine converts its own result to affine) or 1.
• CB: sign-context index width.
• SH: 1 sends all hashing to the external port sha_ext.

Trait Implementations

impl<const NFB: usize, const NSHA: usize, const NSC: usize, const NCP: usize, const CB: usize, const SH: usize> Clone for ScalableSignCore<NFB, NSHA, NSC, NCP, CB, SH>

where W<CB>: BitWidth,

fn clone(&self) -> ScalableSignCore<NFB, NSHA, NSC, NCP, CB, SH>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<const NFB: usize, const NSHA: usize, const NSC: usize, const NCP: usize, const CB: usize, const SH: usize> Debug for ScalableSignCore<NFB, NSHA, NSC, NCP, CB, SH>

where W<CB>: BitWidth,

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

Formats the value using the given formatter.

impl<const NFB: usize, const NSHA: usize, const NSC: usize, const NCP: usize, const CB: usize, const SH: usize> Default for ScalableSignCore<NFB, NSHA, NSC, NCP, CB, SH>

where W<CB>: BitWidth,

Reset state: no key, every context in the free list, all credits available, and each fixed-base machine loaded with the program for the chosen mode. Panics if the parameters break the credit invariants.

fn default() -> Self

Returns the “default value” for a type.

impl<const NFB: usize, const NSHA: usize, const NSC: usize, const NCP: usize, const CB: usize, const SH: usize> Synchronous for ScalableSignCore<NFB, NSHA, NSC, NCP, CB, SH>

where W<CB>: BitWidth,

type S = (<ScalableSignCore<NFB, NSHA, NSC, NCP, CB, SH> as SynchronousDQ>::Q, <DFF<SignRegs<NFB>> as Synchronous>::S, <SignMems<CB> as Synchronous>::S, <[FieldMachine<5, 32, 9, 5, 10, 9, 1>; NFB] as Synchronous>::S, <[ShaRing; NSHA] as Synchronous>::S, <[ScalarRing; NSC] as Synchronous>::S, <[CompressStage; NCP] 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<const NFB: usize, const NSHA: usize, const NSC: usize, const NCP: usize, const CB: usize, const SH: usize> SynchronousDQ for ScalableSignCore<NFB, NSHA, NSC, NCP, CB, SH>

where W<CB>: BitWidth,

type Q = Q<NFB, NSHA, NSC, NCP, CB, SH>

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

type D = D<NFB, NSHA, NSC, NCP, CB, SH>

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

impl<const NFB: usize, const NSHA: usize, const NSC: usize, const NCP: usize, const CB: usize, const SH: usize> SynchronousIO for ScalableSignCore<NFB, NSHA, NSC, NCP, CB, SH>

where W<CB>: BitWidth,

Binds the public ports and the controller kernel.

type I = ScalableSignIn

The type of the input to the circuit.

type O = ScalableSignOut

The type of the output from the circuit.

type Kernel = scalable_sign_kernel<NFB, NSHA, NSC, NCP, CB, SH>

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.
