Struct Pmu 

pub struct Pmu {
    pub spec: PmuSpec,
    pub mode: BankingMode,
    /* private fields */
}

Banked storage with a flat-address interface: the executable meaning of the banking modes.

Fields

spec: PmuSpec

mode: BankingMode

Implementations

impl Pmu

pub fn new(spec: PmuSpec, mode: BankingMode) -> Pmu

pub fn slot(&self, addr: usize) -> (usize, usize)

(bank, offset) of a flat address under a non-duplicating mode: the bank from bank_of, the offset = the address’s rank among the addresses that share its bank — an injective map onto the bank’s words for every address below the capacity.

pub fn write(&mut self, addr: usize, v: i64)

pub fn read(&self, addr: usize) -> i64

pub fn vector_read(&self, access: &AffineAccess) -> (Vec<i64>, usize)

A vector read: the lane values and the cycles it costs (the bank conflicts).

pub fn vector_write(&mut self, access: &AffineAccess, vals: &[i64]) -> usize

A vector write: cycles it costs (bank conflicts; a duplicated write is broadcast, one cycle per lane round since every bank must absorb every lane).

pub fn push(&mut self, v: i64) -> bool

FIFO push (mode must be Fifo); returns false when full.

pub fn pop(&mut self) -> Option<i64>

FIFO pop in push order.

Trait Implementations

impl Clone for Pmu

fn clone(&self) -> Pmu

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Pmu

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