Member Function Documentation

getNumValid()

uint8_t SectorBlk::getNumValid

(

)

const

Get the number of sub-blocks that have been validated.

Returns

The number of valid sub-blocks.

Definition at line 129 of file sector_blk.cc.

References _validCounter.

getTag()

Addr SectorBlk::getTag

(

)

const

Get tag associated to this block.

Returns

The tag value.

Definition at line 148 of file sector_blk.cc.

References _tag.

Referenced by CompressedTags::findVictim(), SectorTags::findVictim(), SectorSubBlk::getTag(), and SectorSubBlk::insert().

invalidateSubBlk()

void SectorBlk::invalidateSubBlk

(

)

Decrease the number of valid sub-blocks.

Definition at line 160 of file sector_blk.cc.

References _secureBit, and _validCounter.

Referenced by SectorSubBlk::invalidate().

isSecure()

bool SectorBlk::isSecure

(

)

const

Checks that a sector block is secure.

A single secure block suffices to imply that the whole sector is secure, as the insertion proccess asserts that different secure spaces can't coexist in the same sector.

Returns

True if any of the blocks in the sector is secure.

Definition at line 135 of file sector_blk.cc.

References _secureBit.

Referenced by CompressedTags::findVictim(), SectorTags::findVictim(), and SectorSubBlk::insert().

isValid()

bool SectorBlk::isValid

(

)

const

Checks that a sector block is valid.

Returns

True if any of the blocks in the sector is valid.

delete

setPosition()

void SectorBlk::setPosition ( const uint32_t  set, const uint32_t  way  )

overridevirtual

Sets the position of the sub-entries, besides its own.

Parameters

set	The set of this entry and sub-entries.
way	The way of this entry and sub-entries.

Reimplemented from ReplaceableEntry.
