Struct HpuDevice

pub struct HpuDevice { /* private fields */ }

Implementations

impl HpuDevice

Provide constructor Use a toml configuration file to properly construct HpuDevice This configuration file contain xclbin/kernel information and associated register map definition

pub fn from_config(config_toml: &str) -> Self

pub fn new(config: HpuConfig) -> Self

impl HpuDevice

Retrieved Hw parameters & configuration

pub fn params(&self) -> &HpuParameters

pub fn config(&self) -> &HpuConfig

impl HpuDevice

Global Key setup

pub fn init<F>( &self, bsk: HpuLweBootstrapKeyOwned<u64>, ksk: HpuLweKeyswitchKeyOwned<u64>, gen_lut: F, )

where F: Fn(HpuParameters, &Pbs) -> HpuGlweLookuptableOwned<u64>,

Convert keys (i.e. Ksk/Bsk) is the correct format Upload them in on-board memory and configure associated register entries Also use the given server key to generate required set of GlweLut Upload them in on-board memory and configure associated register entries

pub fn mem_sanitizer(&self)

Enforce a cleaan state of the HPU before workload execution Currently only enforce proper state of the Ciphertext pool i.e. No already allocated Ciphertext and no fragmentation

impl HpuDevice

Bootstrapping Key handling Only here to expose function to the user. Associated logic is handled by the backend

pub fn bsk_unset(&self)

pub fn bsk_set(&self, bsk: HpuLweBootstrapKeyOwned<u64>)

pub fn bsk_is_set(&self) -> bool

impl HpuDevice

KeyswitchKey handling Only here to expose function to the user. Associated logic is handled by the backend

pub fn ksk_unset(&self)

pub fn ksk_set(&self, ksk: HpuLweKeyswitchKeyOwned<u64>)

pub fn ksk_is_set(&self) -> bool

impl HpuDevice

GlweLut/ Fw handling Only here to expose function to the user. Associated logic is handled by the backend

pub fn fw_init(&self)

pub fn trace_init(&self)

impl HpuDevice

Allocate new Hpu variable to hold ciphertext Only here to expose function to the user. Associated logic is handled by the backend

pub fn new_var_from( &self, ct: Vec<HpuLweCiphertextOwned<u64>>, mode: VarMode, ) -> HpuVarWrapped

Construct an Hpu variable from a vector of HpuLweCiphertext

Trait Implementations

impl Drop for HpuDevice

fn drop(&mut self)

Executes the destructor for this type.
