Detailed Description

template<class T>
class gem5::compression::DictionaryCompressor< T >::UncompressedPattern

A pattern containing the original uncompressed data.

This should be the worst case of every pattern factory, where if all other patterns fail, an instance of this pattern is created.

template<class T >

DictionaryEntry gem5::compression::DictionaryCompressor< T >::UncompressedPattern::decompress ( const DictionaryEntry dict_bytes ) const

inlineoverridevirtual

Decompress the pattern.

Each pattern has its own way of interpreting its data.

Parameters

dict_bytes

The bytes in the corresponding matching entry.

Returns

The decompressed pattern.
