Detailed Description

Range address mapper that maps a set of original ranges to a set of remapped ranges, where a specific range is of the same size (original and remapped), only with an offset.

It's useful for cases where memory is mapped to two different locations

Member Function Documentation

◆ getAddrRanges()

AddrRangeList RangeAddrMapper::getAddrRanges ( ) const
virtual

Implements AddrMapper.

Definition at line 239 of file addr_mapper.cc.

References originalRanges.

◆ remapAddr()

Addr RangeAddrMapper::remapAddr ( Addr  addr) const
protectedvirtual

This function does the actual remapping of one address to another.

It is pure virtual in this case to to allow any implementation required.

Parameters
addrthe address to remap
Returns
the new address (can be unchanged)

Implements AddrMapper.

Member Data Documentation

◆ originalRanges

std::vector<AddrRange> RangeAddrMapper::originalRanges
protected

This contains a list of ranges the should be remapped.

It must be the exact same length as remappedRanges which describes what manipulation should be done to each range.

Definition at line 257 of file addr_mapper.hh.

Referenced by getAddrRanges(), RangeAddrMapper(), and remapAddr().

◆ remappedRanges

std::vector<AddrRange> RangeAddrMapper::remappedRanges
protected

This contains a list of ranges that addresses should be remapped to.

See the description for originalRanges above
