Struct Systolic 

pub struct Systolic {
    pub k: usize,
    pub n: usize,
    pub weights: Vec<i64>,
}

A weight-stationary GEMM tile: k contraction rows × n output columns of int8 MAC PEs, weights baked.

Fields

k: usize

Contraction depth (array rows / dot length).

n: usize

Output width (array cols / outputs per cycle).

weights: Vec<i64>

Stationary weights, k*n row-major: weights[r*n + c] = W[r][c] (int8 range).

Implementations

impl Systolic

pub fn new(k: usize, n: usize, weights: Vec<i64>) -> Systolic

Build a k×n weight-stationary tile; weights is k*n row-major.

pub fn w(&self, r: usize, c: usize) -> i64

The stationary weight held by PE(r, c).

pub fn weight_reads(&self) -> usize

Weight-reads to run an m-row activation stream: k*n — each weight loaded ONCE and reused across all m rows (the reuse a reduction lane lacks, which re-fetches k*n*m).

pub fn cycles(&self, m: usize) -> usize

Cycles to stream m activation rows through the tile: m (one row in, one row out per cycle) — versus m*n*k for a 1-cycle-per-MAC scalar reduction computing the same m*n outputs.

Trait Implementations

impl Clone for Systolic

fn clone(&self) -> Systolic

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Systolic

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

Formats the value using the given formatter.

impl PartialEq for Systolic

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