Constructor & Destructor Documentation

ReplacementPolicy()

ReplacementPolicy::ReplacementPolicy ( CacheABC &  cache, uint32_t  num_sets, uint32_t  assoc  )

inline

Construct a new replacement policy.

Parameters

cache	The parent cache
num_sets	The number of sets in the cache
assoc	The associativity of the chace

Member Function Documentation

getVictim()

virtual uint32_t ReplacementPolicy::getVictim ( uint32_t  set_idx )

inlinevirtual

Determine which line of a range of lines to replace.

Parameters

set_idx

The index of the set to choose from

Returns

The chosen line's way (0 to assoc-1)

Reimplemented in RR, LRU, and FIFO.

printState()

virtual void ReplacementPolicy::printState ( uint32_t  set_idx )

inlinevirtual

Print out the replacer's internal state.

Parameters

set_idx

The index of the set

Reimplemented in LRU, and FIFO.

touch()

virtual void ReplacementPolicy::touch ( uint32_t  set_idx, uint32_t  way_idx  )

inlinevirtual

Notify the replacement policy that a line was just accessed.

Parameters

set_idx	The index of the set containing the line
way_idx	The index of the way containing the line (0 to assoc-1)

Reimplemented in LRU.
