Detailed Description

template<typename V, int max_cache_size = 0>
class gem5::AddrRangeMap< V, max_cache_size >

The AddrRangeMap uses an STL map to implement an interval tree for address decoding.

The value stored is a template type and can be e.g. a port identifier, or a pointer.

addNewEntryToCache()

template<typename V , int max_cache_size = 0>

void gem5::AddrRangeMap< V, max_cache_size >::addNewEntryToCache ( iterator it ) const

inlineprivate

Add an address range map entry to the cache.

Parameters

it	Iterator to the entry in the address range map

iterator gem5::AddrRangeMap< V, max_cache_size >::find ( const AddrRange & r, std::function< bool(const AddrRange)> cond )

inlineprivate

Find entry that satisfies a condition on an address range.

Searches through the ranges in the address map and returns an iterator to the entry that satisfies the input conidition on the input address range. Returns end() if none found.

Parameters

r	An input address range
f	A condition on an address range

Returns

An iterator that contains the input address range

Member Data Documentation

cache

template<typename V , int max_cache_size = 0>

std::list<iterator> gem5::AddrRangeMap< V, max_cache_size >::cache

mutableprivate

A list of iterator that correspond to the max_cache_size most recently used entries in the address range map.

This mainly used to optimize lookups. The elements in the list should always be valid iterators of the tree.
