Member Function Documentation

get_absolute_max_power_threshold()

double TofinoMauPowerSpec::get_absolute_max_power_threshold ( ) const

inlineoverridevirtual

Implements MauPowerSpec.

get_concurrent_latency_contribution()

int TofinoMauPowerSpec::get_concurrent_latency_contribution ( ) const

inlineoverridevirtual

For computing latency contribution of a MAU stage.

Implements MauPowerSpec.

get_cycles_to_issue_credit_to_pmarb()

int TofinoMauPowerSpec::get_cycles_to_issue_credit_to_pmarb ( ) const

inlineoverridevirtual

Implements MauPowerSpec.

get_deferred_ram_read_power()

double TofinoMauPowerSpec::get_deferred_ram_read_power ( ) const

inlineoverridevirtual

Implements MauPowerSpec.

get_deferred_ram_write_power()

double TofinoMauPowerSpec::get_deferred_ram_write_power ( ) const

inlineoverridevirtual

Implements MauPowerSpec.

get_deparser_max_phv_valid()

int TofinoMauPowerSpec::get_deparser_max_phv_valid ( ) const

inlineoverridevirtual

Implements MauPowerSpec.

get_deparser_throughput_scaling_starts()

int TofinoMauPowerSpec::get_deparser_throughput_scaling_starts ( ) const

inlineoverridevirtual

For scaling MAU power based on deparser buffer depth. The deparser limits how many PHVs may be traversing the MAU pipeline simultaneously.

Implements MauPowerSpec.

inlineoverridevirtual

The additional power given when –disable-power-check is provided at the command line.

Implements MauPowerSpec.

get_map_ram_read_power()

double TofinoMauPowerSpec::get_map_ram_read_power ( ) const

inlineoverridevirtual

Implements MauPowerSpec.
