Detailed Description

Base class for encoders.

The goal of encoders is to provide an alternative representation to values, ideally shorter than the value. The alternative representation is called a code.

Member Function Documentation

decode()

virtual uint64_t gem5::compression::encoder::Base::decode ( const uint64_t  code ) const

pure virtual

Decode a value.

encode()

Parameters

code	The encoded value.

Returns

The original value.

Implemented in gem5::compression::encoder::Huffman.

encode()

virtual Code gem5::compression::encoder::Base::encode ( const uint64_t  val ) const

pure virtual

The function responsible for the generation of the alternative value.

If the size of the returning Code is greater than the maximum undelying type's size (e.g., 64 bits) the encoding results should be discarded.

Parameters

The	value to be encoded.

Returns

The encoded value.

Implemented in gem5::compression::encoder::Huffman.
