Fields

core_arch: HpuNttCoreArch

Core architecture

min_pbs_nb: Option<usize>

Minimum #PBS in the batch for full throughput

batch_pbs_nb: usize

#PBS in Ntt Pipe

total_pbs_nb: usize

Maximum #PBS store in Pep

ct_width: u32

Bit width of ciphertext modulus (pow2 modulus)

radix: usize

Implementations

impl HpuNttParameters

pub fn stg_iter(&self, poly_n: usize) -> usize

pub fn ls_delta(&self) -> usize

Trait Implementations

impl Clone for HpuNttParameters

fn clone(&self) -> HpuNttParameters

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for HpuNttParameters

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for HpuNttParameters

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl FromRtl for HpuNttParameters

fn from_rtl(ffi_hw: &mut HpuHw, regmap: &FlatRegmap) -> Self

impl PartialEq for HpuNttParameters

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

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

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

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

impl Serialize for HpuNttParameters

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
