Struct Registers 

pub struct Registers {
    pub prefix_cv: [b32; 8],
    pub epoch: b64,
    pub first_batch: b64,
    pub batches: b32,
    pub count: b32,

    pub seed: [b32; 8],
}

Host-written configuration: the kernel’s arguments.

Written over AXI4-Lite before start and frozen while running. Together, prefix_cv, epoch and the batch range first_batch .. first_batch + batches decide every key the run makes, which is why the host must never repeat them (see the module notes).

Fields

prefix_cv: [b32; 8]

Derive-key prefix CV (8 × 32 bits, secret, write-only): the BLAKE3 chaining value from which every one-time key of this signer is derived. Args cv0..cv7 at 0x070 + 4w.

epoch: b64

Epoch (64 bits): part of the run’s namespace; mixed into every key and into every certificate envelope.

first_batch: b64

First batch id (64 bits): the number of the run’s first 128-key batch. Batch ids are part of the namespace.

batches: b32

Batches to make (32 bits). Each batch is 128 keys.

count: b32

Messages to sign (32 bits). The run is done when this many frames have been acknowledged by HBM.

msg_base: b64

Message base address (64-bit HBM byte address, 4 KiB aligned).

out_base: [b64; 8]

Frame base address per slice (64-bit HBM byte address, 2 KiB aligned).

seed: [b32; 8]

Ed25519 seed words (32-bit halves; 8 × 32 = 256 bits, secret, write-only): the certificate signing key. Args seed0..seed7 at 0x090 + 4w.

Trait Implementations

impl Clone for Registers

fn clone(&self) -> Registers

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Registers

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

Formats the value using the given formatter.

impl Digital for Registers

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 dont_care() -> Self

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 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 binary_string(self) -> String

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

impl PartialEq for Registers

fn eq(&self, other: &Registers) -> 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.
