Constructor & Destructor Documentation

ZeroRun()

gem5::compression::FPC::ZeroRun::ZeroRun ( const DictionaryEntry  bytes, const int  match_location  )

inline

Definition at line 171 of file fpc.hh.

Member Function Documentation

getRunLength()

int gem5::compression::FPC::ZeroRun::getRunLength ( ) const

inline

Get the number of zeros in the run so far.

Returns

The number of zeros in this run.

Definition at line 189 of file fpc.hh.

References _runLength.

getSizeBits()

std::size_t gem5::compression::FPC::ZeroRun::getSizeBits ( ) const

inlineoverride

Definition at line 179 of file fpc.hh.

References _realSize.

setRealSize()

void gem5::compression::FPC::ZeroRun::setRealSize ( int  size )

inline

When the real size is set it means that we are adding the main zero run pattern.

When that happens, the metadata length must also be taken into account for the size calculation.

Parameters

size	Number of bits used to represent the number of zeros in the run.

Definition at line 206 of file fpc.hh.

References _realSize.

setRunLength()

void gem5::compression::FPC::ZeroRun::setRunLength ( int  length )

inline

Set the number of zeros in the run so far.

Parameters

The	number of zeros in this run.

Definition at line 196 of file fpc.hh.

Member Data Documentation

_realSize

int gem5::compression::FPC::ZeroRun::_realSize

private

A zero run consists of a main ZeroRun pattern, which has a meaningful real size (i.e., different from zero), and X-1 fake (i.e., they are zero-sized, and don't exist in a real implementation) patterns, with X being the size of the zero run.

_runLength

int gem5::compression::FPC::ZeroRun::_runLength

private

Run length so far.
