Enum SfpuKind 

pub enum SfpuKind {
    Exp,
    Recip,
    Rsqrt {
        eps_nano: u64,
        over: usize,
    },
    Silu,
    Relu,
    Ln,
}

The SFPU’s element-wise repertoire. A new transform is a new KIND, never a new ComputeOp.

Variants

Exp

Recip

Rsqrt

1/sqrt(x/over + eps) — the divide happens ONCE, here. See RowXformKind::Rsqrt for why scale-once is part of the contract rather than something a reduction’s scaler may absorb.

Fields

eps_nano: u64

over: usize

Silu

x · sigmoid(x) — one fused SFPU instruction on Tensix (silu_tile).

Relu

Ln

The natural logarithm — the inverse of Exp, which no composition of the others reaches. The GDN decay (1+e^u)^R is exp(R·ln(1+e^u)): a real power needs a real log.

Trait Implementations

impl Clone for SfpuKind

fn clone(&self) -> SfpuKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SfpuKind

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for SfpuKind

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for SfpuKind

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for SfpuKind

fn cmp(&self, other: &SfpuKind) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for SfpuKind

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

impl PartialOrd for SfpuKind

fn partial_cmp(&self, other: &SfpuKind) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for SfpuKind

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
